Yes, Bush is crazy enough to use nukes, because for a man who feels - and is - a nobody, it would be the ultimate power trip.

There are no good strategic reasons for using nukes, and plenty of good strategic reasons not to use them:

1. A 1kT yield is militarily useless against bunkers. Larger yields would do the job, but being ground bursts, would potentially spread fall-out all the way into Russia, Pakistan, Saudi Arabia, Turkey and Israel, depending on which way the wind was blowing. Some parts of Wales are still dealing with the fallout from Chernobyl, so ignoring fall-out is really not a good idea.

2. 1kT is bad enough. Using anything as a tactical bunker buster more could really, really, really piss off the rest of the world.

3. The bunker buster idea is nonsense. All you get is a conventional nuke going off under the minimal cover of 10-20ft of rock. In terms of cratering and fall out, the difference between this and a ground burst are minimal.

4. The Pentagon apparently believes it can keep the Strait of Hormuz open. This is fantasy. It can't.

...And so on. You can make a long list proving that the idea is suicidally stupid. But Bush is suicidally stupid. So reality is not the issue here.

The bigger question is how the rest of the world, especially Russia, China, India, and the Saudis, responds. So far, no one is saying anything, which makes it very hard to tell.
