I cannot respond fully to the mix of support, constructive criticism and acerbic witticism that greeted my essay in these pages. I see five main arguments in these responses. First, the United States cannot restrain itself; its behavior is natural and normal. Second, my general and specific guidance will find no support either in the U.S. public or policy elite. Third, the changed relationship with specific regions that I suggest will leave those regions worse off from a security point of view; the states there will be unable to manage; and that this will ultimately redound to the disadvantage of the United States. Fourth, there are plenty of good things the United States can do with its power, if it behaves with just a bit of moderation. Fifth, the potential destructive power of nuclear weapons in the wrong hands overshadows any political gains the United States might accrue from restraint, and indeed necessitates that it actively suppress the diffusion of the technology that permits the acquisition of nuclear weapons to any state with which it has disagreements.
