When I was a little girl, at the height of the Cold War, I used to wish, deeply and fervently, that nuclear weapons had never been invented. An accompanying fantasy placed me at the center of world events. Just as the two superpowers were preparing to launch a devastating exchange of nuclear weapons, I would step between the two. Seeing an innocent child, the hard-boiled men of the world would soften and reconsider their terrible course.

In other words, at the age of 7 or 8, I was a liberal. As I grew, I came to understand a) that it was not possible to put the nuclear genie back in the bottle, and b) that the way to safety lay not in arms control but in strength prudently pursued.
