Not as ridiculous as it sounds, with Russian aggression in the East failing to be punished by our cowardly establishment, the rise of far right groups and economic difficulties a return to the nation state will see a lot of useless quarrels over territory (as Russia in Sevastopol)
I'm more concerned about the UN, Nato and Eu doing absolutely nothing to curb Russian excesses.
Some precedent we've set there... Invade whoever you want we won't do anything.
