Where's Osama?

According to 9/11 Commissioner John Lehman, he's living safely in Pakistan, still receiving money from his Saudi family. But don't worry, although this guy is pretty sure where he is, he's also pretty sure that we couldn't capture him because he's with so many like-minded terrorists who will protect him, and then something about Vietnam. Whatever. It's sad how the Vietnam references fly when it comes to catching Osama, but they're shunned when mentioned in the context of Iraq. So let me get this straight: We know where he is, but we can't kill him because there are too many people around him that are also bent on reigning Holy terror on America? Does that make sense to anyone else? Where's the 'war' part of the War on Terror?
