Ironically, only a far left state could do this. Rightoids in the west are deluded by Christianity and will be vehemently against seizure of property and extrajusticial killing and imprisonment. The left however are the most bloodthirsty and revolutionary. An atheist leftist with complete totalitarian control over the state could turn a European state cometely white in a few days by mass deportation, suppression via police and ethnic cleansing under the justification of "fighting reactionaries". Europes only chance is with the second coming of Joseph Stalin.
