Sure, with the war should not be fair bit, I suggest the following changes.
1. There is a random chance when the war goes active that all your weapons are transformed into flying monkeys. They are completely useless in combat but you are unable to get rid of them. They require large quantities of bananas (other food products) and randomly steal other country stocks, particularly jewelry.
2. Blackout periods cannot be set and are completely random.
3. Wars are randomly declared by player countries on other player countries. This happens regardless of war levels and any kind of war protection. These wars go active immediately.
Wars are not necessarily fair based on many factors but there should be understood rules that apply equally to both players. Arguing that a given player should not be able to lose because the map is not paintable is ridiculous.
