And the question shouldn't be "can Ukraine win", it should be "why do we give a shit?". Seriously, why do we care? Why are we propping up an undemocratic regime? Why do we care about artificial borders? Why don't we re-draw them based on the traditional allegiances people have?
Can't we learn from Yugoslavia that these "carved up countries invented by world powers" simple aren't sustainable?
Can't we learn from Iraq that these "forever conflicts" aren't about saving anyone, they don't care if millions die as long as they make $billions from it.
