Sure. partition a country against its will.
Otherwise, what are adjacent countries going to do with all of those anarchists and neo-Nazis in western Ukraine on the loose?
The adjacent countries have similar numbers of neo-Nazis.
Has Ukraine shown any aptitude for governing itself? If it shouldn't be partitioned against its will, the people of eastern Ukraine should not be forced to stay in the Ukraine against their will.
Do I feel the same way about the US? Yes. If it gets so bad that states want to vote for their independence, they should be able to do so.
It seems the coup leaders immediate action was to go whining to the US, NATO and EU for financial and military help. That's why I said they should be put out of their misery as a nation. They don't seem to want independence, they want a new piggy bank.
