Which is more of a threat, the bear actually threatening to eat you or the one an ocean away?
And to make things more interesting, which is worse for the world, the country doing their damnedest to make climate change worse or the one that has essentially single-handedly made solar power a viable alternative?
Source on the abandoning decreasing emissions? They're shuttering coal plants, starting the world's largest hydro electric project, pumping out the next generation of EV cars, massively funding green tech etc. And I'm hard pressed to find anything comparable in America's course.
And sure, bears can swim but few can do so over an ocean. Even a casual understanding of modern history or an ounce of common sense should show you how much easier it is to invade a country next door than it is to maintain supply lines across an ocean.
