Coupled with Turkey's invasion of northern Syria, Washington's recent announcement that the US will keep up to 2,000 troops in Syria indefinitely marks another turn for the worse in the country's seven-year conflict. It also highlights the incoherence and recklessness of US policy.
One stated reason for keeping US special forces in Syria is that the US wants to prevent a resurgence of the Islamic State (IS). Another is that the US needs to block Iran's penetration of Syria. Both arguments are flawed.
