Let's see how the leftist uprisings have gone before:
The Spartacists, led by Rosa Luxemburg and Karl Liebknecht, were a group of radical socialists who found 'fame' in the first few months after the November Armistice when Germany experienced its so-called 'Revolution'.
OK, going well so far...
In December 1918, some of the Spartacists - including Luxemburg and Liebknecht - founded the German Communist Party.
OK, good good...
German government and hugely suspicious of anything that smacked of left-wing political beliefs. Many who had quit the German Army joined the right wing Free Corps (Freikorps). These would have been battle-hardened men who had been subjected to military discipline.
Ooo.... not so good. It's kind of like all the returning vets from Iraq and Afghanistan coming home after the leftists in the Barry administration lost both wars after they fought and bled to win them...
In January 1919, the Communists rose up in revolt in Berlin. In every sense it was a futile gesture against the government. Ebert withdrew his government to the safety of Weimar and allowed the Freikorps and what remained of the regular army to bring peace and stability back to Berlin once again. No mercy was shown to the Spartacists/Communists whose leaders were murdered after being arrested. The Freikorps was better organised and armed - they also had a military background. The majority of the Spartacists were civilians. No-one doubted who would win.
AND that exactly what would happen with a leftist revolt in this country. Well, maybe not the murdered red leaders... maybe...
But... one can hope...
