From the Harvard Law School Bulletin's interviews with alumni in public service (Fall 2002 issue), two perspectives:

Caspar Weinberger '41: "People keep saying, 'But what is enough and how much is enough [in the military budget]?' And the only answer to that is, 'If you don't have enough, you'll never know it until it's too late to do anything about it.'"

Michael Dukakis '60: "If I had become president? I think there'd be peace in the Middle East."
