I don't think they had a choice with Turkey, Russia, Syria, and the U.S. against them.
They really had no choice. They were used to fighting with the benefit of Air Support, artillery support, Special Operations support, and intelligence, surveillance and reconnaissance (ISR) support, against enemies that had little to none of those things. Facing the Turks without US, they found out what it is like to be on the other side of that fight.
