Considering how bipolar we are as a nation, it could range anywhere from “eh, no one got hurt” to wiping everyone off the face of the planet.
What happens when the US gets accidentally bombed by Israel and 34 people are killed? They talk it out and remain good friends.
The US government and the elite they represent do not care about the American people beyond them being the tools by which they can force the world into as steep a hierarchy as possible with the US elite on top. If the US gets bombed, the US government will do what serves the interests of the US elite.
So it really depends on what’s convenient. It’s hard to speak generally about an alternate universe in which Canada and Mexico are at war, but if I squint my eyes I can say that if Mexico hit the US, the US would invade Mexico and install new leadership while conveniently using it as a reason to suspend the midterms and ramp up to a full-blown genocide of Latinos in the US; while if Canada hit the US, they would be made to pay a trillion dollars in reparations or something.
it would react completely hypocritically and blast everyone for even trying to launch weapons that weren’t sold to them from us.
Why dont you try it out?
Tell both of them the exact coordinates of a place/person you dislike, and your credit card number, and then watch what happens.

If that happened, we’d call it an excuse to annex someone.
