I think you overestimate the latitude fascists have to make policy, given the context of fascism. Any fascist coming to power in the US was naturally going to gravitate away from alignment with our traditional allies - even those as close and cooperative as Canada - and seek bombastic attacks on both traditional allies (showing 'strength') and traditional enemies. Since Russia and Israel are supportive of US fascism, and China is economically powerful, that leaves only a handful of targets.
Not only that, but where do you get the idea that MAGA chafes under his Middle Eastern policy? The only MAGA that are chafing under his Middle Eastern policy are the actual neonazis who hate Israel for being Jewish, which are a small proportion compared to the Christian nationalists who want Israel to be supported unconditionally to trigger the end times. And don't get me started on what they think about bombing Middle-Eastern countries.
