Strictly-objectively speaking, "Turkish-American alliance" died the minute those moronic American officials decided to support terrorist groups in ME that threaten Turkish security. Those groups are even openly in bed with Russia and Iran but for some unknown ..ing reason America still protects them. Nowadays they even train said terrorists with MV-22B Ospreys and Bradleys.
They don't have any Mideast policy whatsoever, They dug their own grave and now they're paying for it. They lost Turkey and Iraq, and possibly soon enough they're going to lose the Gulf as well. These countries will keep the existing military ties of course, but that will be it. The U.S. will only have Israel on their side for obvious reasons but even then that's only a one sided alliance.
The hegemon is clearly losing blood fast. The downfall is not going to happen anytime soon due to the sheer size of their power, but at least they're now dead set on going that path.
The funniest thing is the US is supporting Marxist insurgents in both Syria and Iran. Namely the PKK in Syria and the MEK in Iran.
That isn't even the worst of it with regards to Turkey. The attempted coup against Erdogan a couple years ago also has all the hallmarks of being sponsored by the US.
The US policy in the Middle East is pretty simple. Keep the local powers weak so the oil can be extracted cheaply. For much the same reason Libya was destroyed.
I suspect within this generation we will see another major war in the Middle East. And it will be Egypt and Turkey against Israel.
The US collapse as a global hegemon is still not assured but the US political class sure seem to be working on making it happen.
The funny thing is, all they had to do to stay in Turkey's good grace was to keep their existing policies. I.e. don't try to tip the balance in the Aegean, and don't ever support terrorist groups, whose goals are to try to split the country. To give you some context, those groups present themselves to the West as representatives of the Kurds but their actions mainly effect Kurds (suicide bombing, killing civilians, etc.).
would you look at this load of crap?
And then they have a "surprise pikachu face" reaction whenever these weapons end up in the hands up their non-state adversaries:
(who then end up shooting down passenger planes, of which even the threat that is presented is a HUGE issue.)
These dumbasses don't have any sort of Middle East policy whatsoever. All they do is alienating their allies and pushing them to the other side.
