The method of harsh reprisals and collective punishment, besides being morally bankrupt, actually has a pretty bad track record. The Nazi's in occupied Yugoslavia, among other places, had a policy of executing 100 random civilians for every German soldier killed. But this had the exact opposite impact on the resistance movement, actually increasing resistance sentiment.
Would be interesting to compare the nazi methodology with the Russian way of war in chechnya. Russia seemed to get submission through not very nice means.
They both tended to use locals to do their dirty work. For example in Chechnya they didn’t use many “Slavic” Russians but mostly Allies from Chechnya or ex-republics of the CCCP. The nazis also recruited locals.
