And while Western Europe was at peace...
* Hungary was enduring a Bolshevik Revolution (the Hundred Days of Bela Kun) in 1919, during which tens of thousands of Hungarians were murdered by the Reds.
* Hungary, Romania, and Czech armies continued fighting throughout the "peace negotiations," trying to capture as much territory as possible, making their new borders a fait accompli.
* Soviet Bolsheviks attacked Poland in February 1919, a war that lasted until 1921.
* And a big civil war was raging in Russia, which would claim more deaths than Russian losses in WW I.
If not for The Freikorps, Germany may very well have gone Bolshevik.
Unfortunately The Freikorps became a big part of what was to become The National Socialist German Workers Party.
