Not as pleasant as you might think. World War II happened anyway. The USSR under Stalin invaded Poland, Finland, Japan, and the Baltic States in 1938, then Germany (the Weimar Republic was hardly able--or willing--to defend itself), and drove the Allied armies all the way back to the Pyrennees and the English Channel. The US and UK signed an armistice in 1940 on unfavorable terms rather than try to continue with what they saw as a lost cause. The Great Depression continued until the early 1960s and the Sino-Soviet Empire very nearly won that world's Cold War (there the historians call it the Protracted Struggle) until it fell apart in a bloody welter of ethno-nationalist counterrevolutions all over two continents. It's a much less affluent world than our own, and Western popculture is all bubblegum escapist fantasies about an imagined golden age before the war. In the year 2010 Warsaw and Paris are still bombed-out wastelands, but rumor has it that the US-Australasian Alliance has plans to put a man in orbit by the end of the next decade.

>>11, what's it like in the parallel universe where H. Ross Perot was elected US President in 1992?
