I felt he was alive all this time.
Otherwise this would have been over before the Oscar show.
My guess is they are already 99% certain he is dead, but you will NOT hear any top US figures say anything official for some days. They will NOT need to find a body or DNA to confirm it. We will be able to tell in lots of other ways.
In my opinion, I think they got him this time. There are too many confident US officials speaking out tonight. Much more than on the 19th. They said they knew what floor they were on in this building, the number of people and that they were within 4 feet (meters) of each other. They had FOUR (4) different intelligence leads they were there at this time. 3 on the ground and 1 electronic. I think they may have gotten him.
If they have gotten him tonight, and we get the WMD evidence in a couple of days, this will strike fear into every terriorist leader in the world. Bush can just about get whatever he wants from any world leader. Otherwise he will sic the special ops and military on you. This is a new kind of war.
