We don't even know if the Syrians were the ones who released them. It may very well have been Al Qaeda who made it look like it came from the Assad government. Assad is no angel, but nothing about 0bama's entire administration has been true so far. Also, Russia was supposed to be the country who was reponsible for collecting said chemical weapons. They've already shown they have no respect (or fear) of any other country, especially us. They don't particularly care about the UN, either.
