That was the case in many countries. In France for example a huge part of the resistance was way too sympathetic with Stalin's ideas (and btw didn't join the resistance up until 1941 and Hitler's operation Barbarossa, when Hitler betrayed Stalin) so one of the very first thing the government did in France right after WWII was to disarm the resistance as much as they could. Most people don't read about that but it's well documented.
These (back then) superpowers were paranoid and rightfully so: the cold war started right after WWII and both blocks were very careful not to have ennemies from within.
