I desperately want this to be true just because I'm a political junkie and a student of history and it'd be a great start to the week to see the White House, State department, Pakistan, and everyone else respond to it. Definitely rooting for a Charlie Rose interview of Hersh. But there does seem to be only one main source he relies on and the whole story and its details just seem so perfect.
It will be interesting to see if his story is corroborated in the weeks and months to come.
