History is full of examples where if the victor ignores or continues to grind down the vanquished after formal hostilities have ended, all you do is foster smoldering resentment and sow the seeds for the next war. Magnanimity and inclusion after the war turns this around and old enemies then have a way of turning into new allies in surprisingly short time frames. However, this is precisely what did NOT happen at the end of World War I. The Treaty of Versailles that ended World War I was a deeply, deeply hated and heavy boot on the neck of the Germans, mostly because the French and some other allies wanted it that way as punishment. Germany was stripped of some lands, the air force was disbanded, the Navy was gutted, the German economy crashed, and people starved in the streets of Berlin. In addition Germany was saddled with huge war reparations that had to be paid back over decades. This created smoldering resentment, especially among unemployed former German soldiers and when a fiery charismatic leader arose from those ranks, Adolf Hitler, people were willing to listen to what he had to say. 21 years later, it was back on again when Hitler attacks Poland. At the end of World War II, the Allies this time resolved to do things differently, mostly thanks to George Marshal. History records this was a wise choice. You should be able to take it from there.
