The agreement President Recep Tayyip Erdogan secured with Russian President Vladimir Putin on Oct. 22 complements his recent green light from US President Donald Trump for Turkey’s military incursion into Syria against the formerly US-backed People's Protection Units (YPG).
Erdogan has in effect secured Moscow’s acceptance of Turkey’s Operation Peace Spring against the YPG, launched Oct. 9. Ankara considers the YPG a Kurdish terrorist organization that threatens its security.
