executions were inside the party though, or did 'les purges' now intertwined with collectivization and ww2 ethnic deportations in your brain? cause directly deaths cause by stalin are not in millions range, they are around 1.5-2.5 (700k in purges, 800~2000 in deportations in totality (again debatable what is the attribution of ww2 to hard conditions, but sure). famine is very debatable to be caused by one man, deaths in prison never have been attributed to country leaders, or i would like obama death count to be amended by 30k dead prisoners.
leaving aside that, vietnam war killed two millions, people don't clutch their pearls over lbj or jfk fans, how come?
