So I saw a theoretical plan for Ukraine winning by the summer.
There are a lot of Russian soldiers, and ethnic Russians in Crimea. Crimea is fed by an irrigation system for food, this accounts for 85-90% of the food in Crimea. The flood gates used to control the irrigation are in Kherson. The speculation is we hold out opening the irrigation gates and potentially 3 million ethnic Russians and soldiers will be without food. This in a military whose logistics wing is literally public and rife with mafia members who take bribes to not be good logisticians.
