So, the Russians, the Iranians, and the Turks sat down in a room to "resolve" the civil war in Syria. Needless to say, the chief objective of the Russians and the Iranians is to keep Bashir al-Assad in power. Turkey, a purported NATO "ally," is anxious to cooperate with Iran to achieve its own most cherished goal: suppression of the Kurds.
Tr*mp, of course, admires Erdogan's style of leadership; but America's stubborn loyalty to an undeniably autocratic Erdogan seems to have just one real objective: maintaining the US presence at Incirlik Air Base in Turkey. To do that, both the Administration and military leaders seem willing to empower both Iran and Russia. Iranian client Hezbollah appears to have solidified control over Lebanon, Iranian ties to the al-Abadi regime in Iraq are stronger than ever, and we can assume Russia's military occupation of Syria will expand: without US support, Kurdish control of northern Syria is doomed.
Now that Erdogan has destroyed the secular legacy of Ataturk, the Kurds are the only ones in the region willing to keep government separate from the practice of Islam; and even though Turkey is Sunni and Iran is Shi'a, Erdogan and Rouhani see no impediment to uniting against the Kurdish "threat." Haider al-Abadi will happily join the club, anxious to gain control of Kurdish areas of northern Iraq. America's fourteen-year investment of lives and money in Iraq will have been entirely wasted.
The Kurds, after a century of oppression, deserve to have an independent homeland; and it is in the best interests of the US that they succeed in their quest. Deserting them now only means more regional power for Russia and Iran, and diminished US influence in the Middle East.
