If the enemy is fueld by hatred and some sense of our pride... and we open up to them and say 'yeah, we did some bad shit and it won't happen again'...
at least some % of the enemy is going to feel pacified and focus their energies on killing each other instead of coming at us. Can't be a bad thing if the muslim world loves obama - the prez is the face of a country - and if they like him, they like us, which keeps our troops some % safer.
Plus, we alreday know how the old way works.
