Ukraine is losing citizens, that do not seem to be comitted to Ukraine as a state. World community (or West) can keep an empty shell within 1990 borders but that would be very peculiar "state"..
So when civilians flee an unprovoked invasion, it justifies that invasion in your opinion as the country isn't a real country anymore because a significant part of the population fled the war? That's just insane.
If the citizens are not commited to their country what is the point of that country's existence? ..
If armed assailants enter my house, I'm going out the back door and running to a neighbor's to call 911. That doesn't mean I'm "not committed" to my house, it means I'm sane.
so there should be one country on the planet, because ultimately only US has enough force to defend..
