Although there are news stories about catastrophes there and the use of chemical weapons on their own civilians, I believe that we just got out of some very long and horrible wars and it is hard to justify using force again. I think taking the chemical weapons is a good move.
What would the purpose of American intervention in Syria be? American entry into the war would ramp up hostilities and lead to more people dying. A defeat would be embarrassing to America so we would fight until we removed the current government. A peaceful resolution would no longer be possible. After removing the government we would have to set up a new one and that process isn't exactly going smoothly in either Iraq or Afghanistan. We must let Syria solve its own problems.
