Osama Bin Laden is not well read and he's not sophisticated, but he will have worked out very coldly what America would do in response to this attack 9/11. I'm sure he wanted America to attack Afghanistan. Once you do what your enemy wants, you are walking into a trap, whether you think it's the right thing to do or not.
Why is it that we go to immense lengths getting the Serbs who were responsible for the massacre of 7,000 at Srbrenica-that's slightly more than the total figure for New York 9/11-and we take them to a tribunal in The Hague, and one after another, we arraign them, try them, convict them, and punish them in front of the world, but no plans have been brought forward to get Osama bin Laden and his friends and put them on trial.
