Don't forget that a lot of the "smart" bombs and missiles (like the ones we've been using on Iraq lately) have been, shall we say, less than accurate. I've read several reports in the newspaper about "smart" and guided weapons going astray and missing targets.
So, I don't believe air warfare is the answer, although my initial gut reaction on Tuesday was "let's go nuke 'em!".
After thinking about it more, and seeing the devolpments on CNN, et al., it just seems that going in with troops is prolly the only way to go. YES, it means Americans dead, but guess what? You sign up for military, you understand and accept the fact that you could be called into active combat and killed. There's a reason the Armed Forces throw so much money at you when they try to get you to sign up.
And did anyone hear the latest? The legit Pakistani (I believe it was Pakistani, anyway, although it may have been one of it's neighbors) government pledged the support of 15,000 ground troops if America decides to go in. I like them odds!
