Yes, I think this will be a messy conflict. However, it is something we had to do. Afghanistan has basically told us to go screw ourselves since about the 12 of September. They've tried to dictate terms to the most powerful nation in the world, and we weren't having any of it. What we were asking was real simple...extradition of somebody involved in crimes committed in the US.
Before you as for evidence linking him to the attacks on the 11th of September, that doesn't matter. We don't NEED evidence of that. Bin Laden has already been indicted for previous attacks, and has claimed credit for them. So whether he was responsible for recent attacks or not (which it is fairly reasonable to think he was), he was responsible for previous attacks, and for that alone he should be extradicted.
As a member of the military, I have no problem with what is going on. These guys have spit in our face, then smiled. So now we're going to punch them in their collective mouths. I love this country, and I hate to see it pushed around. I have no problem risking my life to do this.
I suggest everybody do this: tape a video of the World Trade Center falling. Stick it on the shelf. Any time you have second thoughts about our involvement in any of these operations, put it in, watch it, and remember that there are a few thousand Americans dying on your TV screen.
And final note to morons: not all Muslims are terrorists. Not all Muslims support terrorists. Muslim Americans, especially, do NOT tend to support terrorists. Just as not all Christians supported Hitler. And no, I am not Muslim.
