Lenin lives long enough to form a Dynasty.
Lenin lives longer, and has a son whom he grooms for leadership whom comes to power in 1937. The son having travelled in the West, and throughout the world takes a more pragmatic approach in regard to the Red Army, and relations with Germany. Never trusting, he refuses the offer to occupy Eastern Poland. He can read German and he does not trust Hitler, so, when the Germans attack, they go up against a prepared Red Army on Soviet soil, and the Blitzkrieg stalls. The war in the east quickly turns into a stalemate. Without German success against the USSR, Japan does not attack the US, but instead only goes after the Dutch East Indies. Eventually, Germany simply goes bankrupt, running out of both money and manpower to fight the USSR, while Japan holds on to Manchuria, Korea, Indonesia and other areas. China is withdrawn from by all outside parties, but is given enough weapons to fight a nasty 20 year Civil War. Germany is never truly invaded, but instead sues for peace and falls apart as its constituent parts fight for dominance. The USSR, unified, but tired from a long war rests for a decade. It never becomes a Super Power, but neither does the USA, which has set out this series of wars. Instead the world continues with a multiple of powers including a freed but Fascist France, loosely allied with Germany, but deep down hating them, a screwed up Nazi State, more a failure than anything, though they never will admit it (and a global pariah as what they did to their own citizens comes out), and the USSR sandwiched between Germany, a still shaky China of one Political bend or another (I do not know whom would win a very long civil war) and Japan, frustrated but still armed to its teeth.
