Kibbutzs existed before Israel for one but if you can say it is an element of settler colonialism on one hand and say that the USSR and Warsaw pact countries weren’t russified on the other with a straight face while knowing about Russian backed separatist movements in Georgia, Ukraine, and Moldova at a minimum, not to mention the large Russian population in Baltic nations, what happened to Crimea during the Soviet Union, and why Kazakhstan has a large Russian speaking population you have a very weird set of double standards. As for the Soviets wanting National Liberation within the Warsaw pact you might want to look at the history of what happened in Hungary in the 1950’s, in Ukraine and Poland before world war 2 and during where they were forced to join the USSR by military occupation, what almost happened to Finland, why Romania and Yugoslavia set up defenses against land invasions from the Soviets and the list goes on, not to mention the border disputes with China, or what are called the color revolutions during the last years of the Soviet Union. The Soviet Union was a colonial empire but not like that of the US or the UK but more like that of the mongols, Romans, or Chinese, cultures who expanded their borders not just for resources, but to implement their culture and defensive borders. Yes the US has a somewhat homogenous culture, but much of that can be attributed to Hollywood and mass distribution of media (and the genocide of indigenous peoples in the 1800’s), Communists had those too but also controlled all media, enforcing propaganda and language norms, such as forcing the Magyar and ukranian languages into lower positions within their own countries in comparison to Russia for everything from education to government processes, similar to what france did in the last 300+ years with its internal languages and cultures, and China has been enforcing the dominance of the Han culture for close to 2000 years and has been getting rid of local languages for decades now to promote Mandarin.
