There isn't a single accepted definition of what fascism is. The USSR and their left-wing allies in Western Europe would define everything that wasn't communist as “fascist”. It still continues to this day.

I'd suggest you read about fascist Italy to get a sense of what fascism is. So far I haven't seen Democrats repeatedly kicked out of cars in Times Square after drinking a bottle of castor oil. Trump said that he wouldn't look to be reelected for a third mandate.

The Iran war is mainly a consequence of the Israeli influence on US politics; it has nothing to do with fascism, and it is in continuity with the previous administration.

So yeah, populism likely, a plutocracy (evidenced by the role of AIPAC in elections) but not fascism.
