Denmark needs to evict american soldiers and reclaim those bases.
After sewing their assholes shut.Stuff 'em with poutine and Molson until they burst?
Ireland, Austria, Malta. That’s it. (Even some of the Austrian political parties are moving towards supporting NATO membership.)I'm not sure how many EU nations aren't in nato, but I know some ARE, and they are largely incentivized to protect each other... so, most of the EU would go to war one way or another if article five is triggered.
Also the last time the US fought Canada, they torched the White House IIRC. Though Mar-a-lago would require a bit longer trip this time...Canada inspired a pretty sizable chunk of the Geneva Conventions. Nobody's really in a hurry to be reminded of how.
