After reading about various German WWII atrocities, my question always was as per the thread title: “Were the Germans planning on living in Europe after they won the war and pissed off almost all of their neighbors?” Let me show you what I mean.
This is sample Nazi Victory scenario, be free to substitute your own if it helps you answer.
You are the leader of Fascist Germany (you don’t care about Nazism per se, Just what is good for Germany and your continued rule) in 1951, you occupy a bunch of nations that hate you -- now what?
Background: after managing to defeat the USSR, but not the Commonwealth (aided by American Lend Lease) Nazi Germany is the master of continental Europe. In August 1945 a truce is declared with the UK. Hitler’s health (being a drug addict) continues to decline and he dies of a heart attack in 1948. It has taken you 3 years to become the new Fuhrer.
Nazi Germany occupies countries from France to the Urals, but the American and British lead in A-bombs make further military conquest impossible. Although there is a lot of heated rhetoric, currently there is trade between the Fascist bloc (Europe) and the rest of the world. Italy’s scandal plagued and wobbly Fascist government is in danger of falling and joining the Anglo-American diplomatic camp, if not in danger of holding free elections outright.
In 1951 there is a rising generation of Germans who have known nothing but victory and growing prosperity and have no identification with the grievances that drove the Nazis into power back during the ancient days of the Great Depression. They dream of having the life style similar to that of an American teenager, a dream which the new German prosperity is starting to put into reach, they do not dream of farming the Ukraine or occupying Norway.
Here are the options as I see them, each worse for Germany than the last
1)
Act the same as the Soviet Union in OTL and sign the Berlin Pact of fascism and have an Iron Curtain . Problem: The Soviets had to keep under control a handful of low population states in Eastern Europe. There will have to be German bayonets from the Atlantic to the Urals indefinitely. Including probably Italy. Every couple of years there will be a crisis somewhere and Germany will either have to crush the locals, with all the bad PR that entailed (The attraction of communism basically died in the 1956 Hungarian crack-down) or grant concessions (like with Polish Solidarity – and that lead to problems for the Soviets too). In some areas of Europe, especially in the east, this promises to be a particularly expensive and thankless task.
2)
Declare Victory over Bolshevism, redraw the map of Europe and then go home. Except that German brutality has left a lot of enemies, more even than even the withdrawal of the Soviets in OTL. Despite the Treaties, where Germany leaves, a potential anti-Nazi government springs up, (perhaps Spain and some Balkan allies being the exception). Also it is not going to take the Europeans long to trade atrocity stories and figure out what went on in those concentration camps and how extensive it was. Germany will be surrounded by a ring of pro-Anglo-American foes.
3)
Form a Fascist EU with Germany in the Driver seat. By supporting home grown fascist movements Germany can create a “Common European home for Fascism". I think of this as the Gorbachev option and we know how well that worked. Without German bayonets, reform Fascism probably does not work any better than reform Communism works in OTL. There is simply no way a peacetime 1950s Norway gives popular approval to a fascist government even to get the benefits of joining the EU. With no Jews or Communists around, the local fascist cannot run against those bogeymen, so they will have to win approval on the merits of fascism and the German alliance.
4)
Mein Kampf-colonize the East; because a bad plan is better than no plan. How many people in 1950s Germany had lots of kids and can be lured by the promise of ‘free land’ to a life on the Russian Steppes? Probably just a trickle. I can possibly see Germany absorbing Poland, but there is no way Germans can Aryanize all of Europe. What is the government going to do, force Germans to procreate at gunpoint?

Ship them against their will to points east? I won’t go into what world and European reaction to this scheme (and keeping the concentration camps going against the Slavs) would be during peacetime.
5)
Loot Europe. Since Germany is the richest part of Europe, how is this to work exactly? Send the products of the German Education and prosperity to Greece to crack heads and extort olive oil. I mean it would be cheaper for Germany just to buy the stuff or even give out big loans

. I can really see the German youth of the 1950s-60s wanting to be a big part of this occupation scheme.
So What would you do?
