Had any of these events foiled Lenin, our own times would be radically different. Without Lenin there would have been no Hitler. Hitler owed much of his rise to the support of conservative elites who feared a Bolshevik revolution on German soil and who believed that he alone could defeat Marxism. And the rest of his radical program was likewise justified by the threat of Leninist revolution. His anti-Semitism, his anti-Slavic plan for Lebensraum and above all the invasion of the Soviet Union in 1941 were supported by the elites and the people because of the fear of what the Nazis called “Judeo-Bolshevism.”
Without the Russian Revolution of 1917, Hitler would likely have ended up painting postcards in one of the same flophouses where he started. No Lenin, no Hitler — and the 20th century becomes unimaginable. Indeed, the very geography of our imagination becomes unimaginable.
The East would look as different as the West. Mao, who received huge amounts of Soviet aid in the 1940s, would not have conquered China, which might still be ruled by the family of Chiang Kai-shek.
