I had been plunged into a different world. I found myself spending half my time answering weird questions on book tours in the Midwest. People would stand up and explain to me the situation in their office and ask me whether they should resign or not.
And beyond that, the next issue is how do we guarantee one of these weapons, not necessarily this missile, but nuclear weapons ends up in the hands of Al Qaeda or some other terrorist group.
I just learned not to take a single thing for granted, and I think it just is extraordinary.
