Sly move, Obama, sly move.

This assumes that it was Assad who authorized the use of such weapons. Given that it is at least equally possible that the rebels were the ones that used them - based on other CW attacks against Syrian loyalists - it might very well come out that the GOP stopped an attack that would have killed innocent people. Time will tell.
