These Genocides of 12 million Ukrainians in 1921 and 1931 included several hundred thousand Mennonite and other fundamentalist German farmers that committed the error of settling amongst Lenin's and Stalin's enemy.

This is the Big Bang of the 20th Century because WWII and the Cold War were the tragic consequence of this unknown World War 1.5.
