Wrong on all counts. Your assumption that “only we” can provide the troops demonstrates a fundamental ignorant of the sizes of the Muslim state military in the Gulf States and Egypt.
I think you mean ignorance. And at least I'm not ignorant enough to believe that Trump could manage to make his fantasy safe zone happen without a substantial U.S. troop commitment. Even Trump himself said he'd get the Gulf States to pay for it. He didn't say he'd get them to provide troops.
