Putin spent $2 trillion Rubles fixing up Crimea, building up its military bases, and inviting Russians to move there from the mainland. He built the famous Kerch Strait Bridge which he himself inaugurated. Now the whole peninsula is F-ed with no water. How are they going to wash the Kinzals?

No, it was definitely not Russia.

Ukraine, OTOH, has been trying to destroy Crimea by depriving it of water ever since Russia annexed it. They finally got their wish. Imagine that.
