I love how people take the Soviet revolution as some sort of example of success, when what actually happened was that the original government collapsed because it was getting the shit kicked out of it by Germany, then a new government took over and got the shit kicked out it of by Germany before also collapsing, then the Bolsheviks strolled into literally empty government buildings and took over - against the judgement of most of the Bolsheviks who still thought the time wasn't right to take over. Hardly a replicable or generalizable sequence of events.
