I am so outraged over this, I am at a loss of words to express it. The ONLY scenario that I can come up with on this is that Obama took personal offense because Karzai did not come to meet him at Baghram, so he released some prisoners from Gitmo that would make Karzai’s life hell. Yes, he really is that petty.
My mind followed similar thinking to yours. Not sure we’re right, but given who’s involved, chances are at least 50-50.
