Going to LA

I'm actually a little scared about coming to LA this weekend. I believe there was a congressional report saying that there would likely be a terrorist attack in the U.S. by the end of the year, and I think they mentioned Western U.S as a possible target. Thanksgiving is awfully close to the end of the year, and, if I were a terrorist, I'd be pretty tempted to hit it on a holiday.
Apparently, there is a chance that Pakistan may not have their nukes guarded effectively (or maybe that's just our government's cant on the issue, hoping to get Pakistan to reveal some information to us about their nuke program).
Musharraf's not an idiot. Foolish, maybe, possibly power hungry, but not an idiot. So, what would he do, given this hypothetical scenario: Taliban gained possesion of a Pakistani nuke? He'd probably declare an emergency, and martial law; he'd do whatever he possibly could to track down the weapon or those who did it.
I guess the question I'd like answered is, what is our government's motivation for wanting to assisst Pakistan guard their weapons? Is it simply an intel tactic, or is there a real danger of a nuke falling into the wrong hands?
Whatever the motivation, the 1984ish fear control tactic seems to be working, at least for me. I'm actually scared to travel in my own country.
