My boss/best friend, who believes that Bush is 180 degrees wrong in how the country is going, lost a brother-in-law in the World Trade Center. His thoughts on the reappearance of Osama Bin Ladin is, "Why the fuck is this guy still alive?" The boss is very much against the war in Iraq and sees it as a tremedous distraction in the war on OBL.
My thought is that Iraq was necessary in that it attacked the spectre of WMD armed terrorists from the other angle. If OBL would have been a cunsumer of WMD, then it looked to all the world that Saddam would have been the supplier. OBL: the Will, Saddam: the Way. If you can look at the terrain of Tora Bora, one chain of mountains endlessly after another, one should be able to see that we could have sent in the entire Army, Marine Corp, Navy, and had the Air Force doing air recon, and we would still be looking for him while fighting every militia in the area.
Then again, and the boss and I are in complete agreement on this one, is that if you took down the back dropp behind Bin Ladin, you would have seen the swimming pool and back yard of the Pakistani Presidential Palace.
