I ' m a bit late to answering this but the short of it is that it is not clear what the Nazi long term plans were regarding the South Slavs or really the Slavic population of Eastern Europe as a whole . Furthermore , the war time policy towards occupied Yugoslavia suggests that the Nazi did not regard the South Slav population as one particular group but rather as many different groups most likely a mix of both pragmatic political considerations and racial ideology . First of all , the problem with the Nazis ' antiSalvism is that beyond the general view of Slavs being racially inferior there is not much to in overall coherent political practice . Vis a vis Poland , the Nazis ' policy was to eliminate their intelligenzia in order to make the Poles a sort of slave people to the Germans as well as to resettle large portions of the Polish population from certain areas in order to clear for German settlers . Vis a vis the population of the Belorussian , Ukrainian , and Russian parts of the Soviet Union , the German government did plan to let between 20 and 30 million people starve in order to feed the German population as laid out in the Generalplan East . They did not fully institute this plan and in the end it was mainly the Soviet POWs who fell victim to it but just the plan itself goes to show that on part of the Germans there was precious little consideration for the lives of Soviet citizens . As for the longer term plans , what would eventually happen to the Poles is a subject of debate and speculation . There are those historians who see traces of a long term plan to eventually kill practically all of the Polish population while others reject this as not having enough of a historical basis . Whatever the long term plans might have been , with regards to other Slavs , policy is less clear . What was planned e . g . for the Czechs beyond serving as forced laborers under the iron boot heel of German overlords is not clear . Similarly , Bulgaria and Slovakia were allies resp . a satellite state of the German regime . While clearly antiSalvic in their ideology , from a political side this let to a significant change in rhetoric vis a vis these countries . Regarding Yugoslavia and the Nazi designs towards its people , the first important factor is that the attack on Yugoslavia was not planned long beforehand but rather a reaction to the coup d ' etat in Belgrad after the Kingdom of Yugoslavia had signed the Axis pact in March 1941 . While the new government under Peter II said they wanted to honor the pact , the Nazis did not trust them and order the attack in order to help the Italians out in Greece . When it came to the how of administering the Yugoslav territories under occupation , the following considerations came into play The country was to be occupied with the minimal amount of military man power possible since the Germans needed all they could muster for the attack on the USSR and their allies had to be considered , Italy , Bulgaria and Hungary were to receive slabs of former Yugoslav territory not only as payment for their participation in the attack on the Soviet Union but also to help out with the first point . A result of this policy was e . g . the foundation of the Independent State of Croatia NDH . Being aware that within the political landscape of the first Yugoslavia , the conflict between Serbs and Croats about political power and autonomy had been a potent one , Croatia seemed like a good territory to mold a puppet state out of . This was helped further along by Italian designs on the Adriatic coast but having not interest in the inner lands . After the peasant party refused to collaborate , the Ustasha was the compromise candidate to lead the newly formed NDH . In the occupation policy of Serbia however , a lot of racist sentiment against the Serbs also historically fueled by Serbia in WWI played a huge role in occupational policy . When encountering resistance in Serbia , the Germans often committed atrocities against civilian population not involved in the resistance with the argument that they were Balkan people , i . e . especially prone to violence and treachery in the Nazi view . In the time frame from September to December 1941 alone , the Wehrmacht shot about 20 . 000 civilians , including the male Jewish Serbs , as part of their campaign of retaliation against Partisans and Chetniks , most of them not involved civilians . In the area of the SaveDrina bend during this action , it was Wehrmacht policy to arrest every male Serb they came across and place them in Concentration Camps while the women and children were forced to flee to the nearby Cer mountains . The Slovenians suffered a different fate under Nazi occupation . Their country was annexed by the Germans and its inhabitants should be forced thourgh a brutal campaign of violence and deportations to be Germanized as they were seen as potentially of a better racial makeup than their neighbors . Based on the notion that by living under Habsburg rule for so long , they weren ' t proper Slavs but rather Germanic tribes speaking a Slavic language , they underwent forced Germanization . So , the general racial policy of the Nazis did not know the category of the South Slav and attitudes between different nationalities differed , even those who were seen as racially better had to suffer tremendously for it . In that sense , it is impossible to say what kind of long term plans there were with regards to Serbians , Slovenes , and Croats . Evidence suggests that they were not seen as one group but rather as a collection of different groups . Sources Walter Manoschek Serbien ist Judenfrei , Mnchen 1993 .
