“Every Conservative desires peace. The threat to peace comes from Communism, which has powerful forces ready to attack anywhere. Communism waits for weakness, it leaves strength alone. Britain therefore must be strong, strong in arms, and strong in faith in her own way of life. The greatest hope for peace lies in friendship and co-operation with the United States of America.”

Source: What is Property? (1840), Ch. V: "Psychological Explanation of the Idea of Justice and Injustice, and the Determination of the Principle of Government and of Right," Part 2: Characteristics of Communism and of Property
Context: Communism is inequality, but not as property is. Property is the exploitation of the weak by the strong. Communism is the exploitation of the strong by the weak. In property, inequality of conditions is the result of force, under whatever name it be disguised: physical and mental force; force of events, chance, fortune; force of accumulated property, &c. In communism, inequality springs from placing mediocrity on a level with excellence. This damaging equation is repellent to the conscience, and causes merit to complain; for, although it may be the duty of the strong to aid the weak, they prefer to do it out of generosity, — they never will endure a comparison. Give them equal opportunities of labor, and equal wages, but never allow their jealousy to be awakened by mutual suspicion of unfaithfulness in the performance of the common task.
Communism is oppression and slavery. Man is very willing to obey the law of duty, serve his country, and oblige his friends; but he wishes to labor when he pleases, where he pleases, and as much as he pleases. He wishes to dispose of his own time, to be governed only by necessity, to choose his friendships, his recreation, and his discipline; to act from judgment, not by command; to sacrifice himself through selfishness, not through servile obligation. Communism is essentially opposed to the free exercise of our faculties, to our noblest desires, to our deepest feelings. Any plan which could be devised for reconciling it with the demands of the individual reason and will would end only in changing the thing while preserving the name. Now, if we are honest truth-seekers, we shall avoid disputes about words.
Thus, communism violates the sovereignty of the conscience, and equality: the first, by restricting spontaneity of mind and heart, and freedom of thought and action; the second, by placing labor and laziness, skill and stupidity, and even vice and virtue on an equality in point of comfort. For the rest, if property is impossible on account of the desire to accumulate, communism would soon become so through the desire to shirk.

1970s, Address to Congress (12 August 1974)
Context: A strong defense is the surest way to peace. Strength makes détente attainable. Weakness invites war, as my generation—my generation—knows from four very bitter experiences. Just as America's will for peace is second to none, so will America's strength be second to none. We cannot rely on the forbearance of others to protect this Nation. The power and diversity of the Armed Forces, active Guard and Reserve, the resolve of our fellow citizens, the flexibility in our command to navigate international waters that remain troubled are all essential to our security.

1950s, Atoms for Peace (1953)
Context: Against the dark background of the atomic bomb, the United States does not wish merely to present strength, but also the desire and the hope for peace. The coming months will be fraught with fateful decisions. In this Assembly; in the capitals and military headquarters of the world; in the hearts of men every where, be they governors, or governed, may they be decisions which will lead this work out of fear and into peace. To the making of these fateful decisions, the United States pledges before you--and therefore before the world--its determination to help solve the fearful atomic dilemma--to devote its entire heart and mind to find the way by which the miraculous inventiveness of man shall not be dedicated to his death, but consecrated to his life.
