Agreed. Anyone with half a brain knows that it’s going to be Canada that takes us into WW3. With the world distracted by all of the other hostile land grabs, Canada will seize the initiative and take Greenland since it’s likely to live up to its namesake soon. This will set off Britain’s alarm bells, and they’ll take Iceland as a hedge against Canuck imperialism. And once Britain is distracted enough, Argentina will be all, “fucking finally” and take the Falklands. Never one to miss an opportunity for oil, the US will decide to preemptively seize Antarctica before the Argentines can expand further… just in time for a few ice shelves to break off and become free-floating. And while the sacrifice of Florida, the Mississippi Delta, and about half of New Jersey will be deemed worth it from the US perspective, the sea level rise will make the previous fighting over islands seem pointless.

All of this is ,of course, contingent on no one being idiotic/spiteful/ignorantly self-righteous enough to launch a nuke. That changes the calculus enough that no mere shitposter doing a prolonged ass-pull could realistically predict beyond “so much for mutually assured destruction.”
