While Musharaff has helped a good amount in the fight, he's walking a razor edge with enemies of his own inside Pakistan. Anything that looks like Musharraf is "allowing" the U.S. to operate inside Pakistan's border is something his own islamic militants can use to turn more popular support away from M and toward them. He's looking at a potential civil war, and we'd rather not cause it. If we lose him in Pakistan, it is unlikely that whoever replaces him would be friendly to the U.S. ~at all~.
So, we're not going to overtly act inside Pakistan, but of course there's been much speculation that we are doing some black ops in there looking for Al Queda. The AQ thugs have been using Pakistan as a sort of "safe house" that they run into, while they re-supply and conduct ops in Afghanistan.
This missile is a somewhat harder to hide operation, if indeed it was us. Which it probably was. So... it's a signal that we really, really wanted that target to blow up. But its a risk, too.
Thank you, Ramius.
Your words have helped me better understand the situation. It’s a dangerous world we live in today.
