Bin Laden has a specific beef with the U.S.--he wants to keep other nations out of the war, so he can focus on the U.S.
Kerry said he wants to get our troops out in Four years, and is determined to do so..he doesn't say "As President I will get them out, in a month, or a year..he says I will get them out in 4 years."
Hmmm, that's interesting... Is that all that you can offer in the way of "proof" to suggest that it's "phoney"? How is it "suspicious" that he would release a video tape now?--it's the perfect time to be doing it. And since there's no evidence that he's not dead, who's to say that he is. Claiming that he's dead or incapacitated when one has no proof of this is a falacious statement. Odd that someone so concerned about the "truth" would be doing such a thing.
There is a large agenda being carried out. Analyzing one vid tape of Osama -- or even all of them, is like trying to fight the fist that is punching you, rather than the body connected to it.
Comparing voice prints from previous video/audio tape to this one will confirm its authenticity. Releasing it on Friday was premature. Waiting until tonight or tomorrow for its release would have given less time to analyze its contents prior to the election.
