While conceding that nations will disagree about when and how to step in as "tyrants ... commit wanton murder," President Obama told the U.N. General Assembly on Tuesday that "we must get better" at preventing atrocities.
The president again laid out his case for strong international action to hold Syrian President Bashar Assad accountable for his regime's alleged use of chemical weapons. Then Obama told world leaders that:
Syria has delivered documents about its arsenal of chemical weapons, meeting a deadline set in the framework agreement between the U.S. and Russia that was announced Sept. 14. The deal calls for destroying all of the weapons by June of 2014. But the country's civil war is showing no sign of slowing down.
