This "information" has not been released without consideration of it's impact on all of the parties involved. Either the information is correct, and the politicians want everyone to know that attacks are imminent, or the information is false and the politicians want to gage the response of all parties. Either way, don't be stunned, this is a multifaceted card game and bluffing is a legitimate strategy.
You got it Victor. Bush, unlike Clinton, is in this to win (I think he has defined that as bin Laden dead) and he's not worried about a temporary dip in his popularity caused by a strategy that results in several delays.
These delays may have several objectives - one might be to see if we can get bin Laden to make a break for a safer hole while the delay is on.....and then we catch him in the open.
Bush has some very scary smart people on his team - I have faith. George, "Lets Roll"...when your ready!
