Reminder: Finland is not a member of NATO. It's not an enemy of Russia like NATO is.
Rather, it's a potential target for conquest.
And Russia and NATO are not enemies. They're each other's best friends. Without Russia, how could NATO recruit new members or justify military spending? Without NATO, how could Russia distract its people from bad leadership?
Just look at how lost the entire global economy has been for the last few decades without Cold War creating endless demand. Look how desperately a few cave-dwelling barbarians have been dressed up as a serious threat. But non-secularized religions are too likely to act rather than just talk, even when they can get their act together, which they usually can't. If global capitalism is to be saved, what we need is a new Red October.
Luckily, Putin seems hell-bent on following in the footprints of the last tsar, so it's mainly a race between which country's populace gets tired of economic troubles first.
