On the eve of the five-year anniversary of the 2011 uprising, lawmakers and former administration officials shared their reflections on the key moments that have shaped recent US policy in Syria. They paint a picture of a president who hoped to guide events on the ground but was never willing to commit the full weight of America's military and diplomatic arsenal to get his way.
