Trump could simply have told the Turks to kiss his big fat orange butt. The Kurds were his fierce allies.
Now Erodogan is forbidding Trump from talking to the Kurds. Erodogan thinks Trump is his bitch now.
Who gives a fuck what Erodogan thinks?
Here is the play by play for you.
Trump says "Kiss my orange butt"
They invade as they were always going to do.
Turkey "generally" try to avoid the limited troops but have orders that they are allowed to defend themselves and if US troops get themselves in the way its their fault.
In being in that area and trying to back up the Turks, US take casualties.
Trump reinforces troops and sends in air support.
They are at war. Unsanctioned war.
Russia comes to back up Turkey
In Europe there is outrage that US attacked a NATO partner and ally. Animus against Trump doesn't factor Turkey's actions because the Kurds are not NATO allies.
NATO disbanded as US withdraws.
The border becomes irrelevabt as the war spills over Syrian borders into Turkey.
Trumps allies and supporters reject his getting into another expensive war. Neo-cons love it secretly but hate Trump so condemn him whilst saying the war must go on. He is booted out of the office and the World gets Mike Pence as President.
Come election time Democrats sweep in.
Recession hits.
Democrats in rebuke of Trump's War, withdraw from the region and tip their hat back at European ex-NATO allies.
Al Bagdadi makes strategic alliances and in the Chaos and anti-American sentiment ISIS makes a comeback.
Meanwhile at I2 Odeon and MOSW both condemn Trump fighting for the Kurds and support Democrats for leaving the area.
