The paradox of Russian borders is that at the current border, and also beyond it, are flat plains. So as soon as they create a "buffer zone" (let's not dwell on what that means for the people in said "buffer zone"), they create a new border... on the same flat indefensible plain. So the next policy goal is to extend the border, etc. Say Russia achieves is "geographic necessity" of conquering Ukraine (which I very much wish doesn't happen). What's beyond there? Romania is a mix of plains and mountains - so what, Russia gets to invade there? Poland is mostly flat and with few major obstacles (Vistula running south-north is probably the only major one - and a very topical one...). So then what - extend the "buffer zone" into Germany? And... Finland? And I mean, you can't trust these warmongering Swedes and Norwegian - remember the Vikings? Better pacify these guys too before it's too late. It's not a logic anyone outside of Russia wants to entertain.
