Ive been wondering about ASB scenarios a bit. Namely wars that are nearly inconceivable. Like a 1930's UK/Soviet war, 30's US/Chinese war, 30's US/Soviet war, US/Fascist Italy war. Random stuff like that.
Anyways, due to the randomness of it all im wondering, do nations actually prepare contingency plans for situations like that? Or do they just not prepare for them due to being so unlikely to happen?
Feel free to post any other obscure warplans for weird situations.
