Well, it looks like the military action that about 80% of Polled Americans are in favor of (Don't throw things at me, I read it in the newspaper) is going to happen, and soon at that.
There's 3 groupings of warships in the gulf (not including the ships that Britain has volunteered to the cause), and just today the US sent about 100 attack planes - F15s and F16s and Bsomething bombers - do an "undisclosed location" (read: Saudi Arabia). It's coming, whether you like it or not.
Operation Infinite Justice has begun. The American Behemoth stirs. Woe betide the countries that stand in it's way!
On a more practical note, keep in mind that a lot of this building up of forces stems from an unspoken demand by the American public to see some of this promised (by Bush) retaliation take shape. He feels that if he continues to do nothing, people will start to say "he's all talk and no action" and he'll lose a lot of the momentum that he has right now.
