Reliquiae Reliquiarum (Remnants of the Remnants)
POD - 1925
Current - 1973
China (Union of Democratic Asian Republic's - UDAR) experiences a revolution to the same effect as Russia (Union of Soviet Socialist Republics), catching the Middle East in the process as well and plunging the Ottomans into a long and disastrous Civil War (Socialist Workers Republics) - hence the French and Brits staying out most of the Ottoman Empire.
Butterflies occur. WW2 happens as close to OTL as possible. Coming to economic grips early on, the USSR experiences its own Civil War (The Great Counter-Revolution as it is known in Russia). It is short and sweet - 6 month conflict, with heavy UN involvement.
Shown is the Comintern ITTL - Before the inclusion of other states after the 1974 Revision of its Charter (Such as the African Federated Republics, and the Bolivarian Union in South America; among many others).
The future from here seems uncertain for communism in Europe. Elsewhere, it seems to be thriving. The world in in semi-terrible shape. The 1st world isn't really suffering much.
Russia, itself (As well as its allies) are a few states that are not to be trifled with. Russia is thriving (albeit with decent US and NATO economic aid for the last 20 years - but not for much longer), meanwhile the Soviet Union to it's west, is decaying on the inside. The first stages of disintegration of the Soviet Union is in T-Minus 6 years, and counting.
