Trump’s desire to disengage from Syria will strengthen the Islamist hand of Erdogan who will not wind up as an opponent of Assad and Russia, but their stooge in northern Syria, and he will keep it - northern Syria, subservient to Assad in many ways, while Erdogan keeps it “quiet” for his own ethnic cleansing benefit.
President Trump's desire, and US disengagement with Syria has nothing to do with the fact that Turkey, Russia and Assad are already cooperating and are not opponents in the areas of mutual interest in Turkey, Syria, Iraq, Saudi quadrangle.
... but their stooge in northern Syria, and he will keep it - northern Syria, subservient to Assad in many ways,...
Yes, Erdogan will be subservient to Russia and have to be nice to Assad, but he will reap a handsome profit for doing so, Erdy will get a cut of the profits from all the future Saudi Group gas and petro pipelines through Syria and Turkey to Greece and Western Europe. Those pipelines will be under Russian control rather than the EU Globalist control that the EU and NATO planned.
while Erdogan keeps it “quiet” for his own ethnic cleansing benefit.
Very likely, the Russians could care less for anyone who cuddled up to the EU while they stole Russian oil and gas, and Assad probably feels the same way about the ISIS terrorists who stole Syrian oil to supplement their US financing. Assad will just have to overlook the Turkish involvement in theft of Syrian oil, but he too will get a cut of pipeline profits and his own oilfields back.
Finally Iran cashes in with free trade route access to the Med. All of this possible because of the Fabulous Obama Regime Arab Spring.
