So?
Pakistan, Russia or China do it too.
The whole idea is that nuclear bombs are supposed to be a deterrent.
If Iran's prime minister is belligerent and threatening, I would say that GWB has set the prime example.

If we bomb them first, we are asking for trouble.
We can't do it just because we THINK at some point in the future they MIGHT do something to one of our allies. If we have any allies LEFT, we can always back them up with a strike.

Under international law, they have a RIGHT to develop their nuclear program. However, GWB is revising international law to his own needs, wants and visions of apocalypse.
