This seems like a sideways trade and in the same spirit. Military defense guarantees, not on the table according to 4 presidents now, could become a possibility for that subset of land which does not require entry into a currently ongoing war. The prior tactic (mere 100's of billions of aid, plus some sanctions) has resulted in the same outcome via a stalemate anyway.

If someone trades territory for a U.S. security guarantee--absent a U.S. base that would have to be bombed by anyone trying to take more of the country--they're an idiot.
