George Marshall Quotes

George Catlett Marshall Jr. was an American soldier and statesman. He rose through the United States Army to become Chief of Staff under presidents Franklin D. Roosevelt and Harry S. Truman, then served as Secretary of State and Secretary of Defense under Truman. Winston Churchill lauded Marshall as the "organizer of victory" for his leadership of the Allied victory in World War II, although Marshall declined a final field leadership position that went to his protégé, later U.S. President, Dwight D. Eisenhower. After the war, as Secretary of State, Marshall advocated a significant U.S. economic and political commitment to post-war European recovery, including the Marshall Plan that bore his name. In recognition of this work, he was awarded the Nobel Peace Prize in 1953.Born in Uniontown, Pennsylvania, Marshall graduated from the Virginia Military Institute in 1901. After serving briefly as commandant of students at the Danville Military Academy in Danville, Virginia, Marshall received his commission as a second lieutenant of Infantry in February, 1902. In the years after the Spanish–American War, he served in the United States and overseas in positions of increasing rank and responsibility, including platoon leader and company commander in the Philippines during the Philippine–American War. He was the Honor Graduate of his Infantry-Cavalry School Course in 1907, and graduated first in his 1908 Army Staff College class. In 1916 Marshall was assigned as aide-de-camp to J. Franklin Bell, the commander of the Western Department. After the United States entered World War I, Marshall served with Bell while Bell commanded the Department of the East. He was assigned to the staff of the 1st Division, and assisted with the organization's mobilization and training in the United States, as well as planning of its combat operations in France. Subsequently, assigned to the staff of the American Expeditionary Forces headquarters, he was a key planner of American operations including the Meuse-Argonne Offensive.

After the war, Marshall became an aide-de-camp to John J. Pershing, who was then the Army's Chief of Staff. Marshall later served on the Army staff, commanded the 15th Infantry Regiment in China, and was an instructor at the Army War College. In 1927, he became assistant commandant of the Army's Infantry School, where he modernized command and staff processes, which proved to be of major benefit during World War II. In 1932 and 1933 he commanded the 8th Infantry Regiment and Fort Screven, Georgia. Marshall commanded 5th Brigade, 3rd Infantry Division and Vancouver Barracks from 1936 to 1938, and received promotion to brigadier general. During this command, Marshall was also responsible for 35 Civilian Conservation Corps camps in Oregon and southern Washington. In July 1938, Marshall was assigned to the War Plans Division on the War Department staff, and later became the Army's Deputy Chief of Staff. When Chief of Staff Malin Craig retired in 1939, Marshall became acting Chief of Staff, and then Chief of Staff, a position he held until the war's end in 1945.

As Chief of Staff, Marshall organized the largest military expansion in U.S. history, and received promotion to five-star rank as General of the Army. Marshall coordinated Allied operations in Europe and the Pacific until the end of the war. In addition to accolades from Churchill and other Allied leaders, Time magazine named Marshall its Man of the Year for 1943. Marshall retired from active service in 1945, but remained on active duty, as required for holders of five-star rank. From December 15, 1945 to January 1947 Marshall served as a special envoy to China in an unsuccessful effort to negotiate a coalition government between the Nationalists of Chiang Kai-shek and Communists under Mao Zedong.

As Secretary of State from 1947 to 1949, Marshall advocated rebuilding Europe, a program that became known as the Marshall Plan, and which led to his being awarded the 1953 Nobel Peace Prize. After resigning as Secretary of State, Marshall served as chairman of American Battle Monuments Commission and president of the American National Red Cross. As Secretary of Defense at the start of the Korean War, Marshall worked to restore the military's confidence and morale at the end of its post-World War II demobilization and then its initial buildup for combat in Korea and operations during the Cold War. After resigning as Defense Secretary, Marshall retired to his home in Virginia. He died in 1959 and was buried with honors at Arlington National Cemetery. Wikipedia

Famous George Marshall Quotes

“When a thing is done, it's done. Don't look back. Look forward to your next objective.”

As quoted in "George C. Marshall and the Marshall Plan: A Model of Transformational Diplomacy" (2005) by Tom Callahan http://web.archive.org/web/20050616023457/http://www.state.gov/r/pa/dc/rks/47848.htm

“The hardest thing I ever did was keep my temper at that time.”

A comment to a personal friend, about Joseph McCarthy's attacks upon his loyalty (which went so far as to call him a "traitor"), as quoted by Alistair Cooke, in Letter from America : General Marshall (16 October 1959), published in Memories of the Great and the Good (1999)

George Marshall Quotes about peace

“I am certain that a solution of the general problem of peace must rest on broad and basic understanding on the part of its peoples.”

Essentials to Peace (1953)
Context: I am certain that a solution of the general problem of peace must rest on broad and basic understanding on the part of its peoples. Great single endeavors like a League of Nations, a United Nations, and undertakings of that character, are of great importance and in fact absolutely necessary, but they must be treated as steps toward the desired end.

“These opening remarks may lead you to assume that my suggestions for the advancement of world peace will rest largely on military strength. For the moment the maintenance of peace in the present hazardous world situation does depend in very large measure on military power, together with Allied cohesion. But the maintenance of large armies for an indefinite period is not a practical or a promising basis for policy.”

Essentials to Peace (1953)
Context: These opening remarks may lead you to assume that my suggestions for the advancement of world peace will rest largely on military strength. For the moment the maintenance of peace in the present hazardous world situation does depend in very large measure on military power, together with Allied cohesion. But the maintenance of large armies for an indefinite period is not a practical or a promising basis for policy. We must stand together strongly for these present years, that is, in this present situation; but we must, I repeat, we must find another solution, and that is what I wish to discuss this evening.

“Discussions without end have been devoted to the subject of peace, and the efforts to obtain a general and lasting peace have been frequent through many years of world history.”

Essentials to Peace (1953)
Context: Discussions without end have been devoted to the subject of peace, and the efforts to obtain a general and lasting peace have been frequent through many years of world history. There has been success temporarily, but all have broken down, and with the most tragic consequences since 1914. What I would like to do is point our attention to some directions in which efforts to attain peace seem promising of success.

“I believe our students must first seek to understand the conditions, as far as possible without national prejudices, which have led to past tragedies and should strive to determine the great fundamentals which must govern a peaceful progression toward a constantly higher level of civilization.”

Essentials to Peace (1953)
Context: I believe our students must first seek to understand the conditions, as far as possible without national prejudices, which have led to past tragedies and should strive to determine the great fundamentals which must govern a peaceful progression toward a constantly higher level of civilization. There are innumerable instructive lessons out of the past, but all too frequently their presentation is highly colored or distorted in the effort to present a favorable national point of view. In our school histories at home, certainly in years past, those written in the North present a strikingly different picture of our Civil War from those written in the South. In some portions it is hard to realize they are dealing with the same war. Such reactions are all too common in matters of peace and security. But we are told that we live in a highly scientific age. Now the progress of science depends on facts and not fancies or prejudice. Maybe in this age we can find a way of facing the facts and discounting the distorted records of the past.

“A very strong military posture is vitally necessary today. How long it must continue I am not prepared to estimate, but I am sure that it is too narrow a basis on which to build a dependable, long-enduring peace.”

Essentials to Peace (1953)
Context: A very strong military posture is vitally necessary today. How long it must continue I am not prepared to estimate, but I am sure that it is too narrow a basis on which to build a dependable, long-enduring peace. The guarantee for a long continued peace will depend on other factors in addition to a moderated military strength, and no less important. Perhaps the most important single factor will be a spiritual regeneration to develop goodwill, faith, and understanding among nations. Economic factors will undoubtedly play an important part. Agreements to secure a balance of power, however disagreeable they may seem, must likewise be considered. And with all these there must be wisdom and the will to act on that wisdom.

“There has been considerable comment over the awarding of the Nobel Peace Prize to a soldier. I am afraid this does not seem as remarkable to me as it quite evidently appears to others. I know a great deal of the horrors and tragedies of war. … The cost of war in human lives is constantly spread before me, written neatly in many ledgers whose columns are gravestones. I am deeply moved to find some means or method of avoiding another calamity of war.”

Essentials to Peace (1953)
Context: There has been considerable comment over the awarding of the Nobel Peace Prize to a soldier. I am afraid this does not seem as remarkable to me as it quite evidently appears to others. I know a great deal of the horrors and tragedies of war.... The cost of war in human lives is constantly spread before me, written neatly in many ledgers whose columns are gravestones. I am deeply moved to find some means or method of avoiding another calamity of war. Almost daily I hear from the wives, or mothers, or families of the fallen. The tragedy of the aftermath is almost constantly before me.

George Marshall Quotes about the world

“We are determined that before the sun sets on this terrible struggle, Our Flag will be recognized throughout the World as a symbol of Freedom on the one hand and of overwhelming force on the other.”

Statement (29 May 1942); The Papers of George Catlett Marshall Vol 3 (1991) by the George C. Marshall Foundation

“The most important thing for the world today in my opinion is a spiritual regeneration which would reestablish a feeling of good faith among men generally. Discouraged people are in sore need of the inspiration of great principles. Such leadership can be the rallying point against intolerance, against distrust, against that fatal insecurity that leads to war. It is to be hoped that the democratic nations can provide the necessary leadership.”

Essentials to Peace (1953)
Context: We must present democracy as a force holding within itself the seeds of unlimited progress by the human race. By our actions we should make it clear that such a democracy is a means to a better way of life, together with a better understanding among nations. Tyranny inevitably must retire before the tremendous moral strength of the gospel of freedom and self-respect for the individual, but we have to recognize that these democratic principles do not flourish on empty stomachs, and that people turn to false promises of dictators because they are hopeless and anything promises something better than the miserable existence that they endure. However, material assistance alone is not sufficient. The most important thing for the world today in my opinion is a spiritual regeneration which would reestablish a feeling of good faith among men generally. Discouraged people are in sore need of the inspiration of great principles. Such leadership can be the rallying point against intolerance, against distrust, against that fatal insecurity that leads to war. It is to be hoped that the democratic nations can provide the necessary leadership.

“I need not tell you that the world situation is very serious. That must be apparent to all intelligent people.”

The Marshall Plan Speech (1947)
Context: I need not tell you that the world situation is very serious. That must be apparent to all intelligent people. I think one difficulty is that the problem is one of such enormous complexity that the very mass of facts presented to the public by press and radio make it exceedingly difficult for the man in the street to reach a clear appraisement of the situation. Furthermore, the people of this country are distant from the troubled areas of the earth and it is hard for them to comprehend the plight and consequent reactions of the long-suffering peoples, and the effect of those reactions on their governments in connection with our efforts to promote peace in the world.

“It is virtually impossible at this distance merely by reading, or listening, or even seeing photographs or motion pictures, to grasp at all the real significance of the situation. And yet the whole world of the future hangs on a proper judgment.”

The Marshall Plan Speech (1947)
Context: An essential part of any successful action on the part of the United States is an understanding on the part of the people of America of the character of the problem and the remedies to be applied. Political passion and prejudice should have no part. With foresight, and a willingness on the part of our people to face up to the vast responsibility which history has clearly placed upon our country, the difficulties I have outlined can and will be overcome.... to my mind, it is of vast importance that our people reach some general understanding of what the complications really are, rather than react from a passion or a prejudice or an emotion of the moment. As I said more formally a moment ago, we are remote from the scene of these troubles. It is virtually impossible at this distance merely by reading, or listening, or even seeing photographs or motion pictures, to grasp at all the real significance of the situation. And yet the whole world of the future hangs on a proper judgment.

“We have walked blindly, ignoring the lessons of the past, with, in our century, the tragic consequences of two world wars and the Korean struggle as a result.”

Essentials to Peace (1953)
Context: We have walked blindly, ignoring the lessons of the past, with, in our century, the tragic consequences of two world wars and the Korean struggle as a result.
In my country my military associates frequently tell me that we Americans have learned our lesson. I completely disagree with this contention and point to the rapid disintegration between 1945 and 1950 of our once vast power for maintaining the peace. As a direct consequence, in my opinion, there resulted the brutal invasion of South Korea, which for a time threatened the complete defeat of our hastily arranged forces in that field. I speak of this with deep feeling because in 1939 and again in the early fall of 1950 it suddenly became my duty, my responsibility, to rebuild our national military strength in the very face of the gravest emergencies.

“Our policy is directed not against any country or doctrine but against hunger, poverty, desperation, and chaos. Its purpose should be the revival of a working economy in the world so as to permit the emergence of political and social conditions in which free institutions can exist.”

The Marshall Plan Speech (1947)
Context: Our policy is directed not against any country or doctrine but against hunger, poverty, desperation, and chaos. Its purpose should be the revival of a working economy in the world so as to permit the emergence of political and social conditions in which free institutions can exist. Such assistance, I am convinced, must not be on a piecemeal basis as various crises develop. Any assistance that this Government may render in the future should provide a cure rather than a mere palliative. Any government that is willing to assist in the task of recovery will find full cooperation, I am sure, on the part of the United States Government. Any government which maneuvers to block the recovery of other countries cannot expect help from us. Furthermore, governments, political parties or groups which seek to perpetuate human misery in order to profit therefrom politically or otherwise will encounter the opposition of the United States.

George Marshall Quotes

“If we proceed in this manner, there should develop a dynamic philosophy which knows no restrictions of time or space.”

Essentials to Peace (1953)
Context: The points I have just discussed are, of course, no more than a very few suggestions in behalf of the cause of peace. I realize that they hold nothing of glittering or early promise, but there can be no substitute for effort in many fields. There must be effort of the spirit — to be magnanimous, to act in friendship, to strive to help rather than to hinder. There must be effort of analysis to seek out the causes of war and the factors which favor peace, and to study their application to the difficult problems which will beset our international intercourse. There must be material effort — to initiate and sustain those great undertakings, whether military or economic, on which world equilibrium will depend.
If we proceed in this manner, there should develop a dynamic philosophy which knows no restrictions of time or space. In America we have a creed which comes to us from the deep roots of the past. It springs from the convictions of the men and women of many lands who founded the nation and made it great. We share that creed with many of the nations of the Old World and the New with whom we are joined in the cause of peace.

“The truth of the matter is that Europe's requirements for the next three or four years of foreign food and other essential products — principally from America — are so much greater than her present ability to pay that she must have substantial additional help or face economic, social, and political deterioration of a very grave character.”

The Marshall Plan Speech (1947)
Context: The truth of the matter is that Europe's requirements for the next three or four years of foreign food and other essential products — principally from America — are so much greater than her present ability to pay that she must have substantial additional help or face economic, social, and political deterioration of a very grave character.
The remedy lies in breaking the vicious circle and restoring the confidence of the European people in the economic future of their own countries and of Europe as a whole. The manufacturer and the farmer throughout wide areas must be able and willing to exchange their product for currencies, the continuing value of which is not open to question.

“I recognize that there are bound to be misunderstandings under the conditions of wide separation between your countries and mine. But I believe the attitude of cooperation has been thoroughly proven.”

Essentials to Peace (1953)
Context: In America we have not suffered the destruction of our homes, our towns, and our cities. We have not been enslaved for long periods, at the complete mercy of a conqueror. We have enjoyed freedom in its fullest sense. In fact, we have come to think in terms of freedom and the dignity of the individual more or less as a matter of course, and our apparent unconcern until times of acute crisis presents a difficult problem to the citizens of the countries of Western Europe, who have seldom been free from foreign threat to their freedom, their dignity, and their security. I think nevertheless that the people of the United States have fully demonstrated their willingness to fight and die in the terrible struggle for the freedom we all prize... I recognize that there are bound to be misunderstandings under the conditions of wide separation between your countries and mine. But I believe the attitude of cooperation has been thoroughly proven.

“I have done my best, and I hope I have sown some seeds which may bring forth good fruit.”

Essentials to Peace (1953)
Context: I fear, in fact I am rather certain, that due to my inability to express myself with the power and penetration of the great Churchill, I have not made clear the points that assume such prominence and importance in my mind. However, I have done my best, and I hope I have sown some seeds which may bring forth good fruit.

“The one great element in continuing the success of an offensive is maintaining the momentum.”

Speech to the Overseas Press Club (1 March 1945)
Context: The one great element in continuing the success of an offensive is maintaining the momentum. This was lost last fall when shortages caused by the limitation of port facilities made it impossible to get sufficient supplies to the armies when they approached the German border.

“The points I have just discussed are, of course, no more than a very few suggestions in behalf of the cause of peace. I realize that they hold nothing of glittering or early promise, but there can be no substitute for effort in many fields.”

“There is a phase of this matter which is both interesting and serious. The farmer has always produced the foodstuffs to exchange with the city dweller for the other necessities of life. This division of labor is the basis of modern civilization. At the present time it is threatened with breakdown.”

The Marshall Plan Speech (1947)
Context: There is a phase of this matter which is both interesting and serious. The farmer has always produced the foodstuffs to exchange with the city dweller for the other necessities of life. This division of labor is the basis of modern civilization. At the present time it is threatened with breakdown. The town and city industries are not producing adequate goods to exchange with the food-producing farmer. Raw materials and fuel are in short supply. Machinery is lacking or worn out. The farmer or the peasant cannot find the goods for sale which he desires to purchase. So the sale of his farm produce for money which he cannot use seems to him an unprofitable transaction. He, therefore, has withdrawn many fields from crop cultivation and is using them for grazing. He feeds more grain to stock and finds for himself and his family an ample supply of food, however short he may be on clothing and the other ordinary gadgets of civilization. Meanwhile, people in the cities are short of food and fuel, and in some places approaching the starvation levels. So the governments are forced to use their foreign money and credits to procure these necessities abroad. This process exhausts funds which are urgently needed for reconstruction. Thus a very serious situation is rapidly developing which bodes no good for the world.

“You know, I know, all of us know that the time factor is the vital consideration — and vital is the correct meaning of the term — of our national defense program”

Speech to the Army ordinance Association (11 October 1939); The Papers of George Catlett Marshall Vol 2 (1986) by the George C. Marshall Foundation http://www.marshallfoundation.org/index.html, Ch. 2 "The Time Factor"
Context: You know, I know, all of us know that the time factor is the vital consideration — and vital is the correct meaning of the term — of our national defense program; that we must never be caught in the same situation we found ourselves in 1917.

“The time has come when we must proceed with the business of carrying the war to the enemy”

As quoted by the Times-Herald [Washington, D.C.] (3 March 1942) p. 1
Context: The time has come when we must proceed with the business of carrying the war to the enemy, not permitting the greater portion of our armed forces and our valuable material to be immobilized within the continental United States.

“For the past ten years conditions have been abnormal. The feverish preparation for war and the more feverish maintenance of the war effort engulfed all aspects of national economies.”

The Marshall Plan Speech (1947)
Context: For the past ten years conditions have been abnormal. The feverish preparation for war and the more feverish maintenance of the war effort engulfed all aspects of national economies. Machinery has fallen into disrepair or is entirely obsolete. Under the arbitrary and destructive Nazi rule, virtually every possible enterprise was geared into the German war machine. Long-standing commercial ties, private institutions, banks, insurance companies, and shipping companies disappeared through loss of capital, absorption through nationalization, or by simple destruction. In many countries, confidence in the local currency has been severely shaken. The breakdown of the business structure of Europe during the war was complete.

“The only way human beings can win a war is to prevent it.”

Various sources below attribute this statement or similar ones to Marshall
But a war to prevent a third world war would be the Third World War, and Marshall had reached the conclusion that, "The only way human beings can win a war is to prevent it."
As quoted in This is Our World (1956) by Louis Fisher, p. 91
Marshall's motto read: "The only way human beings can win a war is to prevent it." It was 1947.
As quoted in The Story of Indonesia (1959) by Louis Fisher, p. 111 http://books.google.de/books?id=AkIeAAAAMAAJ&q=motto+read
Frances Perkins recalled his saying, "The only way human beings can win a war is to prevent it."
As quoted in Freedom's Advocate: a twenty-five year chronicle (1965) by Aaron Levenstein, p. 104 http://books.google.de/books?id=plZIAQAAIAAJ&q=perkins
“Its purpose is to avoid war, not to provoke it,” he explained to his goddaughter, Rose Page Wilson. The deterrence factor was vital. “The only way to be sure of winning a third world war is to prevent it,” Marshall warned.
As quoted in General of the Army. George C. Marshall, Soldier and Statesman by Ed Cray (1990) p. 645 http://books.google.de/books?id=bGgcYteOQxUC&pg=PA645
Unsourced variant: The only way to win a war is to prevent it.
A very similar statement appears in the US Strategic Bombing Survey Summary Report (European War) (30 September 1945), p. 41 http://books.google.de/books?id=mnChmcVKoVsC&pg=PA41&dq=lesson:
:: The great lesson to be learned in the battered towns of England and the ruined cities of Germany is that the best way to win a war is to prevent it from occurring.

“I said bluntly that if the president were to follow Mr. Clifford's advice and if in the elections I were to vote, I would vote against the president.”

Statement indicating his opposition to Clark Clifford's advice to Harry S Truman for the US recognition of the state of Israel prior to UN decisions on the partitioning of Palestine, in official State Department records. (12 May 1948)
If you follow Clifford's advice and if I were to vote in the election, I would vote against you.
Marshall's statement as quoted by Clark Clifford in The New Yorker (25 March 1991)

“Military power wins battles, but spiritual power wins wars.”

As quoted in A Toolbox for Humanity: More Than 9000 Years of Thought (2004) by Lloyd Albert Johnson

“The price of peace is eternal vigilance.”

This has been attributed to Marshall, and he might have used the phrase, but earlier uses exist:
There is an imperialism that deserves all honor and respect — an imperialism of service in the discharge of great duties. But with too many it is the sense of domination and aggrandisement, the glorification of power. The price of peace is eternal vigilance.
Leonard H. Courtney as quoted in The Life Of Lord Courtney (I920) by G. P. Gooch
Courtney's statement however is probably derived from an earlier statement with several variants:
The price of freedom is eternal vigilance.
The price of liberty is eternal vigilance.
Eternal vigilance is the price of liberty.
These have often been attributed to Thomas Jefferson, but also Thomas Paine, Abraham Lincoln, and many others; Alfred Denning in The Road to Justice (1988) states that the phrase originated in a statement of Irish orator John Philpot Curran in 1790: "It is the common fate of the indolent to see their rights become a prey to the active. The condition upon which God hath given liberty to man is eternal vigilance."

“Don’t fight the problem, decide it.”

As quoted in The Wise Men (1986) by Walter Isaacson and Evan Thomas

Variant: Don't fight the problem. Decide it!

“I cannot afford the luxury of sentiment, mine must be cold logic.”

Quoted from George Marshall: Defender of the Republic

“We must stop setting our sights by the light of each passing ship; instead we must set our course by the stars.”
