The president’s red line appears to have been crossed. The administration has to take some time to decide what to do about [Syria’s alleged chemical weapons use]. But if they end up leaving the impression that the president is not willing to enforce his red line, that will have consequences in the region, particularly when it comes to Iran’s nuclear program, as well as for our ability to deter Assad’s use of chemical weapons in Syria.
