"the wall street journal" report that the pent zbon preparing to pull out all u.s. troops from syria by the end of april, even though there is no plan to protect the kurds. joining us now is former ambassador richard haase, the president of the foreign relations, thanks so much for being with us. what do you make of that report? that report says "the wall street journal" says that by the end of april all u.s. troops will be out of syria. >> well, as you say, it's a rhee act of undermining american support for the kurds who were the principal fighters and partners against isis. and it gets back to isis. the idea that you've defeated a terrorist group seems to me to fundamentally misunderstand the nature of the enemy. so if we leave them totally and quickly, it seems to me it only guarantees that groups like isis will reestablish themselves in parts of syria and it's only a matter of time before we find ourselves pulled back in.
