I don't think the US really wants to find Osama. My father was a soldier/pilot and still works teaches at for the Air Force. When I go home to visit most of the troops I talk with are in agreement that as long as Osama Bin Laden is "out there" they'll have more support when they apply for budget increases to replace outdated and dangerous equipment, etc. So you send the minimum number of troops over to do the job, and stick to all the safe spots when conducting a search.

I'm not a general or a politician, but when so many soldiers tell me they'd do things differently (and are generally in agreement on what they'd do differently) you have to ask.

I have more and more respect for our soldiers. Following orders you believe in your heart to be in poor judgement without hesitation, especially when the stakes are so high, is quite admirable. Despite all the parades and TV kudos we give them, we really don't do enough to say thanks.

As for JFK...I can't help but wonder if he'd be remembered as fondly if he wasn't assassinated...or would he just be that generation's Clinton?
Congress moved to have the documents released in the 2020's sometime, but I'm sure by the time the files are made public many will be missing, blacked out, etc.
We may never know.

When I was in school, our history books said that Oswald killed him, period. No question, no debates, no mention of alternative (and more probable) theories.
