But for Turkish who wants to wiped out YPG/YPJ to create buffer zone, you have more possibilities that would happen under Trump presidency.
He tried to pulled US forces out of Syria back in 2019, the decision which made Jim Mattis resigned from his position of SecDef and SDF resorted to Russia and Assad for security guarantee in Manbij which US forces had MSS in Ayn Dadat and Kobani which US had airstrip there (Kobani Landing Zone) in notorious LaFarge Cement Plant (owned by Holcim).
Btw, LaFarge known to paid ‘taxes’ to Islamic State so they could still operational even when the territory still controlled by IS.
