Marc Lynch runs through our options:
The core of the problem is that on its own, the U.S. has very limited leverage over Damascus or events on the ground in Syria. The administration has already done most of the few concrete things which have been suggested by its critics, including sharpened rhetoric, convening an emergency session of the UN Human Rights Council, and preparing targeted sanctions. But since Syria has long been an American adversary in the region, such efforts have limited impact. Rhetoric demanding political change in Damascus will largely fall on deaf ears since most people in the region already assume that the U.S. supports regime change in Syria, and wouldn't have the impact of similar statements about Mubarak, Qaddafi, or Saleh. The U.S. already has a daunting array of sanctions in place against Damascus, leaving it little room for tightening. In short, even the strongest concrete policy proposals on offer are not likely to have much effect on Syria's course.
The UN Security Council is failing to even condemn the escalating violence, which has claimed the lives of more than 450 Syrians in the past six weeks, several of whom are seen in the above video (via Azarmehr).
