Think about it — since the sarin gas is now reported to be mixed and “ready to go,” if the sarin gas has been loaded into bombs, we can’t bomb the bombs. To bomb the sarin gas locations or bomb the bombs will thus release / discharge the sarin gas. If you release the sarin gas by attacking, you will kill thousands in the area. The only choice is to SECURE the sarin gas but who can? and there is a huge time problem.
And think about this: we also can’t wait — because if Pres Assad decides to attack his people, we have no time to protect his people. His people will die WITHIN ONE MINUTE of getting hit with sarin gas.
