I was talking with a conservative friend and the topic of foreign invasion came up. While she strongly believed that one day China, Russia, North Korea (possibly socialized medicine Canada) would one day soon invade and we have to be prepared, I was unable to come up with a country or scenario that was realistic past 1890. All I could think of was a worst case scenario being like that of the (excellent and killed before its prime) TV show Jericho.
Can anyone give a realistic ATL actual invasion on the scale of Red Dawn that could have been successful? Has OTL plans from the USSR been declassified from the Cold War era some place? From what I understand China's military is geared towards a contained Pacific War of short duration against the USA and nothing like being prepared to invade the USA.
