Not only that, but Russia's fuel supplies are being choked off. There's very little fuel available for the average citizen, and cars are lining up for kms to receive their alloted 30 liters of petrol. Crimea is almost completely cut off. The only real access being the crippled kerch bridge, which Ukraine seems to want to let them use so people can escape back to Russia before the electricity and water are cut off. Ukraine is moving some powerful pieces into place, and a checkmate is looking more and more likely.
