Germany sent Lenin in the hopes that he would get Russia out of the war. There is no way Germany would have allowed the Soviet Union to survive after the war. Most of the European territory that became the USSR was handed to them at Versailles. As for Hitler, the German high command sent him to spy and report on the NSDAP, not to revive it. And they wouldn’t have needed to do that if Germany hadn’t lost the war.
Germany would not have attacked the Soviet Union but would have allied with it already having a peace treaty which gave it huge amounts of Russian territory. In addition, the USSR would not have had to endure attacks from Poland. Germany had already succeeded in getting Russia out of the war.
I suggest you look into the German political scene during WWI it is not commonly known that the High Command controlled the party which eventually became the Nazi party long before Hitler left the trenches. Hitler’s spying and reporting on the group does not mean it was not resuscitated. The Army acted on those reports.
There is no question that the defeat in WWI shattered Germany structure to the core and led to the rise of nihilism which produced Hitler. But the war was produced as much by German paranoia as anything else. Its foreign policy was based on the Schliefflen Plan wherein mobilization on either frontier (France or Russia) would cause Germany to attack on the Eastern and Western fronts. One should also recall that Germany had invaded France 40 years before and which had militarism playing a very prominent role in its society for a couple of centuries.
“Most of the European territory that became the USSR was handed to them at Versailles.”
Russia got nothing from Versailles - they were excluded from it; the territory the Germans took, as well as additional territory, was used to create the new (sometimes “renewed”) states of Finland, Latvia, Lithuania, Estonia, and Poland.
Not quite correct.
The ceeded territory was turned into countries or given to other countries, the USSR reconqured the Caucases [ceeded from Ottomans], Ukraine and Belorus in the 1920s and tried for Poland [peacetreaty there in 1925].
The Baltics [independent] and Moldova [Romania] were not recovered by the USSR until 1940/1945.
