War is a highly overrated tool of foreign policy.

The nuclear bomb is the most useless weapon ever invented. It can be employed to no rational purpose. It is not even an effective defense against itself.

It is obviously easier, for the short run, to draw cheap labor from adjacent pools of poverty...than to find it among one's own people. And to the millions of such prospective immigrants from poverty to prosperity, there is, rightly or wrongly, no place that looks more attractive than the United States. Given its head, and subject to no restrictions, this pressure will find its termination only when the levels of overpopulation and poverty in the United States are equal to those of the countries from which these people are now so anxious to escape.

It is an undeniable privilege of every man to prove himself right in the thesis that the world is his enemy; for if he reiterates it frequently enough and makes it the background of his conduct he is bound eventually to be right.

A foreign policy aimed at the achievement of total security is the one thing I can think of that is entirely capable of bringing this country to a point where it will have no security at all.

The jealous and intolerant eye of the Kremlin can distinguish, in the end, only vassals and enemies, and the neighbors of Russia, if they do not wish to be one, must reconcile themselves to being the other.

War has a momentum of its own and it carries you away from all thoughtful intentions when you get into it. Today, if we went into Iraq, like the president would like us to do, you know where you begin. You never know where you are going to end.
