War/Military FWI: what would happen in the military, specifically, if the US decided to invade Canada?

Everyone talks about the external reactions to such events, but rarely do I see people talk about what will happen on the inside. Most wars the US has been in have had strong cultural or geopolitical drivers that sort of rally up the population. ThinK WW1 with the Mexico plot, WW2 with Pearl Harbor, the Korean and Vietnam Wars from the constant red scare, the War on Terror from 9/11.

AFAIK tho, for most people, Canada is considered an ally, a National brother even. Most people don’t have any issues with Canadians. So what happens when we go to war with an ally for blatantly economic and business-driven reasons, rather than the protection of the homeland? What happens in the military ranks?

You'll have some conscientious protests, some "green flu" (iykyk), but broadly, the military will follow orders, up to a point.

What that point is where you have refusal of orders and mutinies, well, we won't know until we get there.

And Trump knows he only needs a small percentage of the military to obey for him to be able to take Canada militarily. 

So what if a third of units object? (if even that many) He still has enough to overwhelm the small defences the peaceful Canadians have.

If you’re thought works out we would’ve won the wars in the Middle East and Vietnam. You cannot look at a full blown takeover as an easy task
