Rostov holds the HQ of the Russian ministry of defense, and is also a major logistics hub.
The idea of a major nuclear power like Russia having a civil war is terrifying, but hopefully Ukraine will be able to take advantage of this.
This doesn’t sound like a civil war. This sounds like a shake up at most.
That’s what I was thinking. Push out all the Russian soldiers (or convince them to switch sides, which seems remarkably easy at this point) while Putin is otherwise occupied. That would end the war, and with so much else on his plate, Putin might think twice about restarting it.
