“I stress the strength of our economy because it is essential to the strength of our nation. And what is true in our case is true in the case of other countries. Their strength in the struggle for freedom depends on the strength of their economic and their social progress. We would be badly mistaken to consider their problems in military terms alone. For no amount of arms and armies can help stabilize those governments which are unable or unwilling to achieve social and economic reform and development. Military pacts cannot help nations whose social injustice and economic chaos invite insurgency and penetration and subversion. The most skillful counter-guerrilla efforts cannot succeed where the local population is too caught up in its own misery to be concerned about the advance of communism.”

1963, Address at the Free University of Berlin

“I appreciate very much your generous invitation to be here tonight. You bear heavy responsibilities these days and an article I read some time ago reminded me of how particularly heavily the burdens of present day events bear upon your profession. You may remember that in 1851 the New York Herald Tribune under the sponsorship and publishing of Horace Greeley, employed as its London correspondent an obscure journalist by the name of Karl Marx.
We are told that foreign correspondent Marx, stone broke, and with a family ill and undernourished, constantly appealed to Greeley and managing editor Charles Dana for an increase in his munificent salary of $5 per installment, a salary which he and Engels ungratefully labeled as the "lousiest petty bourgeois cheating."
But when all his financial appeals were refused, Marx looked around for other means of livelihood and fame, eventually terminating his relationship with the Tribune and devoting his talents full time to the cause that would bequeath the world the seeds of Leninism, Stalinism, revolution and the cold war.
If only this capitalistic New York newspaper had treated him more kindly; if only Marx had remained a foreign correspondent, history might have been different. And I hope all publishers will bear this lesson in mind the next time they receive a poverty-stricken appeal for a small increase in the expense account from an obscure newspaper man.”

1961, Address to ANPA

“These burdens and frustrations are accepted by most Americans with maturity and understanding. They may long for the days when war meant charging up San Juan Hill-or when our isolation was guarded by two oceans — or when the atomic bomb was ours alone — or when much of the industrialized world depended upon our resources and our aid. But they now know that those days are gone — and that gone with them are the old policies and the old complacency's. And they know, too, that we must make the best of our new problems and our new opportunities, whatever the risk and the cost.
But there are others who cannot bear the burden of a long twilight struggle. They lack confidence in our long-run capacity to survive and succeed. Hating communism, yet they see communism in the long run, perhaps, as the wave of the future. And they want some quick and easy and final and cheap solution — now.
There are two groups of these frustrated citizens, far apart in their views yet very much alike in their approach. On the one hand are those who urge upon us what I regard to be the pathway of surrender-appeasing our enemies, compromising our commitments, purchasing peace at any price, disavowing our arms, our friends, our obligations. If their view had prevailed, the world of free choice would be smaller today.
On the other hand are those who urge upon us what I regard to be the pathway of war: equating negotiations with appeasement and substituting rigidity for firmness. If their view had prevailed, we would be at war today, and in more than one place.
It is a curious fact that each of these extreme opposites resembles the other. Each believes that we have only two choices: appeasement or war, suicide or surrender, humiliation or holocaust, to be either Red or dead. Each side sees only "hard" and "soft" nations, hard and soft policies, hard and soft men. Each believes that any departure from its own course inevitably leads to the other: one group believes that any peaceful solution means appeasement; the other believes that any arms build-up means war. One group regards everyone else as warmongers, the other regards everyone else as appeasers. Neither side admits that its path will lead to disaster — but neither can tell us how or where to draw the line once we descend the slippery slopes of appeasement or constant intervention.
In short, while both extremes profess to be the true realists of our time, neither could be more unrealistic. While both claim to be doing the nation a service, they could do it no greater disservice. This kind of talk and easy solutions to difficult problems, if believed, could inspire a lack of confidence among our people when they must all — above all else — be united in recognizing the long and difficult days that lie ahead. It could inspire uncertainty among our allies when above all else they must be confident in us. And even more dangerously, it could, if believed, inspire doubt among our adversaries when they must above all be convinced that we will defend our vital interests.
The essential fact that both of these groups fail to grasp is that diplomacy and defense are not substitutes for one another. Either alone would fail. A willingness to resist force, unaccompanied by a willingness to talk, could provoke belligerence — while a willingness to talk, unaccompanied by a willingness to resist force, could invite disaster.”

“But let me stress again that these are my views — for contrary to common newspaper usage, I am not the Catholic candidate for President. I am the Democratic Party's candidate for President who happens also to be a Catholic. I do not speak for my church on public matters — and the church does not speak for me. Whatever issue may come before me as President — on birth control, divorce, censorship, gambling or any other subject — I will make my decision in accordance with these views, in accordance with what my conscience tells me to be the national interest, and without regard to outside religious pressures or dictates. And no power or threat of punishment could cause me to decide otherwise. But if the time should ever come — and I do not concede any conflict to be even remotely possible — when my office would require me to either violate my conscience or violate the national interest, then I would resign the office; and I hope any conscientious public servant would do the same.”

“I am convinced that the enactment this year of tax reduction and tax reform overshadows all other domestic problems in this Congress. For we cannot for long lead the cause of peace and freedom, if we ever cease to set the pace here at home. For we cannot for long lead the cause of peace and freedom, if we ever cease to set the pace here at home.”

1963, Third State of the Union Address

“No man can fully grasp how far and how fast we have come, but condense, if you will, the 50 thousand years of man's recorded history in a time span of but a half-century. Stated in these terms, we know very little about the first 40 years, except at the end of them advanced man had learned to use the skins of animals to cover them. Then about 10 years ago, under this standard, man emerged from his caves to construct other kinds of shelter. Only five years ago man learned to write and use a cart with wheels. Christianity began less than two years ago. The printing press came this year, and then less than two months ago, during this whole 50-year span of human history, the steam engine provided a new source of power. Newton explored the meaning of gravity. Last month electric lights and telephones and automobiles and airplanes became available. Only last week did we develop penicillin and television and nuclear power, and now if America's new spacecraft succeeds in reaching Venus, we will have literally reached the stars before midnight tonight.
This is a breathtaking pace, and such a pace cannot help but create new ills as it dispels old, new ignorance, new problems, new dangers. Surely the opening vistas of space promise high costs and hardships, as well as high reward.
So it is not surprising that some would have us stay where we are a little longer to rest, to wait. But this city of Houston, this state of Texas, this country of the United States was not built by those who waited and rested and wished to look behind them. This country was conquered by those who moved forward — and so will space.”

“We do not want to fight — but we have fought before. And others in earlier times have made the same dangerous mistake of assuming that the West was too selfish and too soft and too divided to resist invasions of freedom in other lands. Those who threaten to unleash the forces of war on a dispute over West Berlin should recall the words of the ancient philosopher: "A man who causes fear cannot be free from fear."”
