Ethics aside, US must counter Erdoğan or suffer consequences 

For Erdoğan needs the Kurds – or, more precisely, needs a perpetual
war against their democratic political project to distract voters
from domestic economic woes and increasing securitization which has
decimated both civil society and legitimate political opposition in
the country. What is less often recalled is that Erdoğan also
benefits from his love-hate relationship with the US political
administration.
