The isolation of the Syrian Arab Spring is often blamed on Obama for failing to take military action when Syria used chemical weapons & for failing to arm the opposition. You could only hold that view if you believe the US Pentagon is in the business of revolution rather than colonial wars & occupation. The isolation of the Syrian Arab Spring is a result of the complete corruption & collapse of the international left & antiwar movement into an Assadist & Stalinist cult. That corruption manifested in the earliest days of the Syrian uprising based on political capitulation to the rancid ‘war on terror’ narrative.
