I always imagined that Soviet-Chinese relations broke down really bad in the 2050s because China became insane with their conquest of nations. Eventually, they probably tried to take Kazakhstan which started the Sino-Soviet War. In 2066, China made the wrong move and invaded eastern Alaska. The idiot commies awoke a sleeping giant.
Once America joined forces with an unlikely ally, the Soviets, the two quickly took back Australia, the Philippines, Mongolia, South Vietnam, South Korea, etc. (North Korea and North Vietnam joined China willingly). The Chinese were pushed back to Beijing by the allied forces of the Warsaw Pact nations and what remained of NATO (seeing as Europe was a mess of trenches and warring nations by that time). Then, of course, in 2077, we have all out nuclear war.
Overall, I'd say the 'years' concept works better. Additionally, for this timeline to work, China couldn't have had any of their free market reforms in the 1970s. I'd have to say that GNN made an error and President Xin was actually Chairman Xin.
If the US were allied with the Soviets, they probably would've toned down all the anti-Commie rhetoric. More likely is chilly relations between the US, but more or less they left eachother alone- with NATO and the UN disbanded, the US let the Soviets run hog wild across Europe in the Resource Wars. Maybe there was a bit of military adventurism in Africa and the Middle East to secure anything that could be gotten
I'd guess that it was never an official alliance, both countries were fighting their own war against the Chinese, but both had the same goal in mind. There wouldn't be a Soviet consulate in L.A. anyways if the relationship between the two wasn't warm, so I'd say that my explanation is the closest thing to canon.
Outside of the modern games, where is the anti-communist propaganda all that prevalent? All I see is anti-Chinese, not anti-communist.
The Middle East's oil fields were completely dried up and/or set alight before the European Commonwealth could even take them. That, and there was limited nuclear exchange in the Middle East pretty early on, so I'd say it's a barren wasteland with nothing worth acquiring. That, and it's almost certain that the Europeans and the Soviet Union didn't like each other at all, what with the Commonwealth hugging the border of the iron curtain. Nowhere was this likely more prevalent than the Berlin Wall. The Cold War probably eventually boiled down from U.S. versus U.S.S.R. to E.C. versus U.S.S.R.
As a completely unrelated side note, I get the feeling Francoism never left Spain.
Nice fanon, but sadly that's all it is. Personally I think that the Soviet Union became more self centered, like in real life where the USSR was more interested in improving it's relations and economy then taking over the world (yes kiddies, world domination was NOT their goal). However when the Chinese invaded, Russia sent support as it's country started collapsing in a desperate attempt to keep the USSR alive.
Sounds like someone is a bit of a commie.
