I do believe that the Kurds are in a difficult situation. They do have some American support. How consistent that will be is unclear. But they have built up a strong military, and they have begun to build the institutions of an autonomous life in Northern Syria. Turkey's enmity towards the Kurds and their desire to make sure there is no independent Kurdish state or even really autonomous enclave is going to push the Kurds into Bashar Assad's hands over time.
