They would have done it already. Day 1 of invasion they would of cut all major lines. Power sources, communications, food supply. They would of knocked the lights out of the entire country if it were conventional war. The referendum has succeeded.

Any bleeding in Ukraine is due false leadership sensing other peoples sons to die for lies.
