Foreign Policy and the Chicago Council on Global Affairs asked Americans which options they prefer for Syria. The results, as shown above, highlight a pretty large disconnect between the general public and Washington's foreign policy establishment - at least on the question of sending arms to anti-government groups inside Syria.
Another disconnect is evident: the public favors "enforcing a no-fly zone" but not "bombing Syrian air defenses." You usually can't do one without the other.
In any event, it appears the Assad regime is reeling without an overt U.S. intervention.
