Hitler ends up assassinated by Communist Agent somewhere in 1936-1938
Instead of turning into Messy Civil War, Goering managed to gain control relatively quickly and Himmler gets shafted. No war with Poland or anything as the Nazi high command turned to just trying to enrich themselves instead of killing people.
The Soviet Union attacks Finland more or less on schedule, Germany responded by helping Finland by sending 'Volunteers' through the sympathetic Denmark and Sweden (who let German troops went through because they are there to help Finland), Stalin ends up attacking Sweden to cut off German troops and War started with Germany and Scandinavian countries at one side, against the Soviet Union in another side.
Soviet thought they could force Germans to stop aiding Scandinavians by opening the second front through Poland (hoping that Germans would divert most their troops there and thus leaving Scandinavian front easily rolled by superior Soviet numbers), too bad Poland refuse Soviet Troops to pass and then Soviet invaded Poland. Causing Britain and France to declare war against the Soviet Union.
Well, it will go disastrously for the Soviet, as now Germany is getting more financial aid from the allies and start pushing through Poland into Moscow (who are happy to let the Germans fight and die while French and British just limit their military involvement in Naval front and maybe helping the Scandinavians).
Germany did want historical Prussian lands and cut Poland a nice deal, if they wanted sea, they better earn their damn share by invading Ukraine rather than insisting on North Sea access, Poland now think having Black Sea access might be better than having none (or being completely conquered by Germany instead), and started their counter-invasion of Ukraine.
And just to kick Soviets when they are down, Turkey decides to invade the Caucasus to Central Asia and get some Azerbaijan and Turkic People's lands (coupled with Turkic Rebellion there).
Germany now besieging Moscow, with Stalin inside, Poland has taken Ukraine, Turkey carves Soviet Caucasus and Central Asia, while northern Russia being occupied by British-French-Scandinavian forces (who set up a White Russian government there).
And then Stalin ends up captured, get a kangaroo trial in Berlin before executed in a very humiliating fashion.
...
Germany gained some historical Prussian Lands plus several additional ones in the Baltics. Poland conquers Ukraine up to Crimea, and won't let British and French talked them to make independent Ukraine since they wanted Sea Access (and Black Sea is a roundabout way to get them), same with Turkey who basically gobble everything up to Stalingard at the North, all while having 'sister Republic' of Turkmenistan installed in Central Asia. Finland gained favorable adjustments, but there is new Democratic North Russia state located in St. Petersburg. Whatever was left from Moscow was made into a Fascist German Puppet.
Of course, not everyone is happy with now enlarged Germany, but now, ironically Poland is their chief ally (along with Turkey). Finland is rather neutral, if basically pro-Democratic, and the North Russian is furious with how Germany make South Russia separate, but basically can't do anything.
And the stage is set at round 2 of European War, when South Russia tries to attack North Russia.
