Where is our Lawrence of Afghanistan?

It's hard to imagine that our troops will do any better in Afghanistan than the British, the Russians and even Alexander the Great. This is a country that is not hospitable to foreigners. So when I see Gen. McCrystal jogging around the US compound in perfect West Point style I know we're not going to win. History is going to win. My suggestion will never be taken seriously but I think we need a charismatic American leader who steps out of his uniform, grows a beard, goes native, and learns the language. Maybe the Afghans would follow him. But then he would have more power than the Pentagon and that won't happen. But it could turn the trick just as Lawrence of Arabia did in WWI.
