World communism is like [a] malignant parasite which feeds on diseased tissue

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

A guest of one's time and not a member of the household.

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.
