Lets add this up. The Saudis know a heck of alot on Ossama. They monitor huge amounts of phonecalls within the country...and know more than they'd like to admit. If they admit that the guy is dead in public...its a fairly good chance of this being true.
Consider this though...typhoid is beatable...but only with the right drugs. If you were sitting in the middle of Pakistan...in hill country...and could not go to a regional hospital because you were the great Ossama...you would die within 2-3 weeks. Even if this story turns out false...I think the CIA now has a great weapon. If he isn't dead...then bring massive typhoid samples into Pakistan and offer free drugs at the regional hospitals...under guard. You might kill off a couple of thousand of these guys...but considering they aren't helping us in this campaign...I'm not too worried about thier lengthly life.
Let's all sit back and watch this unfold. You still have one or two key members of the leadership around...they must be eliminated as well. We are not done yet.
Doesn't he have a son that is high up, too?
And that is how the administration will need to spin it, i.e. that we kept him on the run away from hospitals and proper medical care, BUT YOU KNOW THAT IT WON'T.
Instead, it will allow the story to be spun that it tool way too long and we basically got lucky.
