I think it has to do more with human nature. You can see a similar mentality with the Russian and French revolutions. The biggest difference is that people aren’t economically desperate here. People may be poor or feel poor but they aren’t truly desperate like Germany in the depression, Russia after the debacle of ww1, France with food shortages, etc. Here it is an ideological and cult of personality issue but not enough to get the majority of people and the major powers (the military, the very wealthy, etc) involved. This feels more like the Red Scare people of the 1950s.
