You know, the way the question was worded made me think that tw wrote it.
This IS a good question though. Like the Taliban, I want PROOF that Osama is most likely behind this. And I'm hearing a lot of different things, but I have yet to see any clear cut evidence that implicates him. The case is indeed building up, but it seems to be a lot of indirect links here and there. I'm not un-American, but I do believe in innocence until proven guilty. If the US has clear-cut evidence, then he should be brought to the Hague for trial.
(Yep, I said the Hague. I can't honestly see Osama bin Laden getting a fair trial in the United States.)
How do we get him out? Afghanistan is like Iraq with mountains. The US would be wise to learn from the folly of the Soviets. Smart bombs and missile attacks on bin Laden's bases seem like a strong first bet. To lob bombs all over Kabul a la Baghdad would be senseless. As far as from there, our safest bet would be to secure the borders, then surround him.
(Please take into effect that I am a war weenie and that I have no extensive knowledge as to planning a military strike.)
And Griff, I wouldn't necessarily be shocked by your friend's response...unless you've had a debate royale over it and the person is still ignorant of the facts.
