That is straight up at odds with American (or Canadian, or for the most part, UK) history. In the United States Trump is the first "war-time" president to blow re-election during an active war, and his term was punctuated by attempts at troop draw down, coupled with inflammatory rhetoric towards Iran when he was low in polls.
Engaging in something that can be spun as a just war is a viable re-election tactic.
Yeah, it's sketchy, which is why I put it in quotes. The reason he is not really a war-time president is the only war he is even close to actually starting is a civil war :P
