All the preplanning for that attack happened in Afghanistan. Rummy wasn't there.
These fools who claim the CIA built up Osama don't know doodly-squat. This should be a lesson to everyone. Don't even TRY to help a muslim under any circumstances, even if he is killing your enemies. After some time, you'll be screwed over for doing it. Just look at Iran-Contra. Where do you think the leaks came from that started all of that?
That's the price for living in Dar-al-Harb (House of War) and being an "infidel".
