For nuclear weapons if it struck a territory the economy would fail not producing IPCs, with any factory there destroyed. Half the infantry die from nuclear fallout with 1 infantry being lost from each boardin territory per nuclear missile. This space can’t be occupied by land units. When a factory is built there all this is undone. I’m not sure about cost but they can move like this,Medium-4, Short 1, Long-7. Antiaircraft guns and fighters can defend against any nuclear missile that go’s though the territory. Fighters can only defend for one round while Antiaircraft guns still work the same. heres where the nukes would be
