This is the worst decision any President can possibly make. But it is calculated. Holding a show trial featuring former President Bush and his administration would be political suicide. But the Obama administration, I believe is doing this to provide a surrogate show trial. Admittedly, this is not my original idea, but it makes perfect sense. The Left has been trying to discredit the Bush administration since September 12 of 2001, with some success. But with falling poll numbers and a sea change in the voting of moderates, something had to be done to take everyone's eye off the ball. What better way than to put these five terrorists on trial in a US courtroom, fully televised where the defense can call Bush administration officials (possibly even the former President himself), CIA operatives, GITMO guards and interrogators and anyone else they see fit. The secrets of US anti-terror operations will be laid bare.
This will backfire. In a big way. It will please the far-left base, but no one else. Our enemies will use this as propaganda. The UN may even use it to conduct "War Crimes Trials" against former President Bush and members of the administration. The public won't like it at all.
I go so far as to call this action by the current adminstration "treasonous".
