The agreement states that if there is noncompliance "or any use of chemical weapons by anyone in Syria, the U.N. Security Council should impose measures under Chapter VII of the U.N. Charter." But it does not specifically state that the resolution being sought now will be under that chapter.
Russia holds veto power on the council. But Kerry told reporters Monday that "Should diplomacy fail, the military option is still on the table."
"If the Assad regime believes that this is not enforceable, then they will play games," he said.
According to the plan, Syria must submit a full list of its chemical weapons stockpile within a week. International inspectors must be on the ground in the country by November, and all production equipment must be destroyed by the end of November.
By the middle of next year, all chemical weapons material must be destroyed, according to the agreement. But the process of securing and destroying Syria's cache of chemical weapons -- in the middle of a civil war -- may be a logistical nightmare.
