i think chemical weapons are most certainly a red line. However, the proof of use of the same must be absolutely certain, and the proper response must come from the United Nations where those weapons were not directly used on us, or against critical American interests. Syrians in far greater numbers have died from conventional weapons of war, and our critical national interests were not threatened, however the use of chemical weapons are a per se war crime, and do threaten everybody, and not necessarily our vital American interests. The proper jurisdiction is the UN. The UN is doing their job sending out investigators. The Syrians have mostly cooperated, and the president must wait for evidence, and then through the UN take action against those responsible. There is nothing inconsistent with the Presidents words and utilization of the proper agency to achieve justice. I do not have the intelligence, but unless the evidence is clear and there is a nexus of threat to American interests, the President is bound to be patient and let the UN process work.
