...there is an optimal balance, depending on the manner of man's life, between the density of human population and the tolerances of nature. This balance, in the case of the United States would seem to me to have been surpassed when the American population reached, at a very maximum, two hundred million people, and perhaps a good deal less.

It is clear that the main element of any United States policy toward the Soviet Union must be that of long-term, patient but firm and vigilant containment of Russian expansive tendencies.

The United States cannot reshape other countries in its own image and that, with a few exceptions, its efforts to police the world are neither in its interests nor within the scope of its resources. This whole tendency to see ourselves as the center of political enlightenment and as teachers to a great part of the rest of the world strikes me as unthought-through, vainglorious and undesirable.

Anyone who has ever studied the history of American diplomacy, especially military diplomacy, knows that you might start in a war with certain things on your mind as a purpose of what you are doing, but in the end, you found yourself fighting for entirely different things that you had never thought of before. In other words, 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.

There is more respect to be won in the opinion of this world by a resolute and courageous liquidation of unsound positions than by the most stubborn pursuit of extravagant or unpromising objectives.

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.

The United States should not jump around like an elephant frightened by a mouse.
