Both Iran and the US consider the use of weapons of mass destruction a grave crime. Indeed, Iran was a major victim of chemical-weapons attacks during its 1980-1988 war with Saddam Hussein’s Iraq. Iran can be a major partner to halt proliferation of WMDs in Syria, the Middle East, and beyond.
Iran maintains that the Security Council is the only body legally authorized to verify allegations concerning the use of such deadly weapons and to decide on the appropriate response. One promising avenue for US-Iran cooperation on Syria could be joint support for a fact-finding mission by the Security Council to identify the perpetrators. Obama has his “red line” on the use of chemical weapons. So does Ayatollah Khamenei.
