There's this telling moment in the Ross Douthat interview of Senator J.D. Vance ("What J.D. Vance Believes"), where Vance is asked when he decided he "liked" Donald Trump, and he cites his first personal meeting with Trump, in 2021, and Trump telling him the story of how the generals tried to fool him into thinking they were obeying his orders to draw down US troops in northern Syria, in 2018-19, by shuffling them around instead:
The media has this view of Trump as motivated entirely by personal grievance, and the thing he talked the most about — this was not long after Jan. 6 — was “I’m the president, and I told the generals to do something, and they didn’t do it.” And I was like, OK, this guy’s deeper than I’d given him credit for. And also I was deeply offended by this. Talk about a threat to democracy — the generals not listening to the president of the United States about matters like troop redeployment.
Actually, it was probably not a general but a civilian, Defense Secretary Jim Mattis in the first place and then Mark Esper. It was a matter of maybe 200 troops out of a total of 2500 US troops in the region, with an extremely specific function: protecting our Kurdish allies (guarding the detained remnants of the Islamic State so it couldn't reestablish itself in the region) from our Turkish allies, who didn't care about the Islamic State, but were eager to get all the Kurds, who President Recep Tayyib Erdoğan regarded as anti-Turkish terrorists, away from the Turkish border; he'd been calling Trump all year, demanding the removal of the US troops so he could conquer all the Kurd-held territory without crossing any Americans, and Trump obediently tried to make it happen, but then the troops didn't actually go away.
Why was Trump so determined to obey Erdoğan's orders and throw the Kurds under the Turkish bus, against the urgent advice of every single member of the national security and foreign policy staff? Perhaps because he so valued his "very good relationships" with authoritarians like Putin, Kim, Xi, MBS, and Erdoğan too? He'd rather have the secretary of defense get mad at him than the president of Turkey. He could fire the secretary of defense (and eventually did, of course, over Esper's refusal to contemplate putting down American protestors with American troops).
But then there's another aspect to Trump-Turkish relations, the "conflict of interest" he mentioned to Stephen Bannon in a 2015 interview:
