Turkey, just like Iran, will never be a convenient target. It has a population way bigger than Iraq and Afghanistan combined, it has a massive, modern, western-equipped military [1] and a huge amount of geopolitical leverage due to its control of the Dardanelles as well as European-Africa-Asia migration routes.

No sane US military leader would attack even if they created a new Sultanate and aligned with Russia or Iran.
