Why won’t the United States do the same? If the United States is investing all this money into Afghanistan anyway, why should there be any concern over prisoners of war — er, detainees — not being tried in Afghanistan? Karzai would probably let the U.S. military run the trials itself.
The important principle to uphold is that no person should be imprisoned without cause, without a just trial. It’s in the Constitution. But that never stopped Dubya.
