Before destroying Syria’s chemical weapons, Assad wants the US to agree to stop arming Syria’s rebels. Larison wishes the administration would take the deal but suspects it won’t:
It costs the U.S. nothing to agree to these terms, but these terms will likely be viewed as unacceptable in Washington. The administration will want to treat its support for the opposition as separate, and it will always want to reserve the option to attack. That isn’t because either position makes any sense for the U.S., but because the administration has trapped itself into commitments that it won’t easily repudiate. The Syrian government may not truly be willing to give up its chemical weapons, but it is doubtful that the U.S. would be willing to accept the exchange that might be required to make the deal work.
