The thread below this got me thinking, what would it take, with a POD after the start of the Cold War and before Gorbachev's ascension to power, to get the United States and Soviet Union to put aside their differences and fight together in a war against a common enemy, how could this come about, how would it effect the US and USSR internally knowing they have to work with their ideological enemy? what would this do for the relationship between the US and USSR, how would it affect the Cold War and the future?
