Eventually. Voluntarily with reparations or after Russian state collapse.
Judging from the state of affairs in the two states in question – the Ukraine and Russia – I highly doubt Russia would be the first one to collapse.
It's Ukraine, not "the Ukraine".
That’s like saying most of Eastern Europe wasn’t part of the Soviet Union. They were just occupied by Soviets for a time. It’s true in an abstract way but not factual.
I highly doubt that in all honesty. But it's good to think positive!
