One has to wonder how history would have been altered if all those masses of Russian soldiers - after destroying the National Socialists, turned their Mosin Nagants and other firearms against the Commissars, NKVD, and other agents of the oppressive Communist state.
Maybe if it they had, we wouldn’t have had to suffer through years of communist butchery in other countries.
Well, there was a sort of dissent among the military after they have seen the West although the steam was kept for a while and finally escaped through Khruschev’s de-Stalinisation.
It is not unparalleled in Russian history. Similar dissent took place in 1820s following Russian repelling of Napoleonic troops and the invasion of France.
There is a nice new movie by 20th Centry Fox: ‘The Union of Salvation’ on this although I have no idea would they release it outside Eastern Europe or not:
