No need for weapons to win a war. Red grows the food and transports the goods. Blue is the consumer. No food or transportation of goods for a month and the country will collapse.
Remember what happened to the people in the Coney Island high rise public housing after Hurricane Sandy. They couldn’t get out cause the elevators stopped working, the toilets overflowed, and the food spoiled after the power went out.
Everybody goes down when the country collapses. That is not necessarily a "Red" victory. I would bet on local warlords taking over for generations.
Way too much "collateral damage" in the transition, meaning too many innocent lives destroyed. Might not be enough left to rebuild an industrial economy.
Not looking forward to any of the pathways.
