No longer a dog, still cool
There wont be any big wars, the reason the cold war never went hot is because neither side's elite wanted to die, specially the soviets: they couldnt give less of a fuck about the people who they constantly killed with famines and gulags, and when not doing that they worked them to death. The problem is that they knew the majority of the nukes were pointed at moscow and the ussr was ridiculously centralized because every party apparatchik wanted to be in moscow and not some backwater town like norilsk. Thats also the reason why moscow was the only city with proper SAM defenses and huge-ass spherical bunkers that could take a direct hit, and on top of that a huge subway network that doubles as fallout shelter. Still they knew they were fucked, that most of ussr would survive WWIII but moscow would become the world's biggest craterEverything is building up to The Last War, the biggest war in human history that will dwarf the World Wars and will either render the human race extinct or usher in a utopia where there's never another war.
You got an even more ridiculous situation with china: their armed forces are literally owned by the party, their objective is not to protect the nation but the party. Needless to say when SHTF many chinese are not gonna die for some ccp fuckhead, and the party knows this which is why they will limit themselves to another cold war and let the average chinese get fucked by global warming and other shit, after all they already killed nearly 100 million of them during the 20th century so whats 100 million more?
