Bush's threats again Iran. Why should Iran care?

I can see it now. Bush gets the Europeans to join him in threatening Iran (Condi threatened them the other day). And so what? Why should Iran care? What are we going to do, invade them with, uh, an army that isn't sufficiently large enough to even fight in Iraq, let alone continue the war in Afghanistan and the relief work in New Orleans and across the south? What "or else" can we legitimately throw at Iran? We're gonna blow up your facilities? Well that's nice. Sounds like a perfect invitation for Iran to send its troops across the Iraqi border and annex a bunch of land. And what would we do in return, go to war against Iran? That'd be special.

I don't see has Bush has any credibility whatsoever to threaten Iran. If Iran has any balls, and they appear to, they'll just up the ante and there isn't a damn thing we can do about it.

That's the cost of trying to do too many unnecessary things. Eventually the necessary things arise and, well, there's no money or manpower or weaponry left. Surprise!
