The only 2 places in the world right now that could turn into a hot war with Russia right now is Syria and Ukraine. Syria is pointless, both sides of that war are shit and not worth backing, its primarily the Saudis(yet again) pulling our chain there. And if you look at a map of Europe, its pretty easy to understand why Russia doesn't want Ukraine to have anything to do with NATO. And if you look at the map again, I'm actually surprised Estonia, Latvia, and Lithuania were ever approved by NATO to join the alliance, those 3 were bound to cause tensions if Russia ever got back on its feet.
Oh boy, we're getting off topic lol.
