This is a loaded question. You’re making the assumption that Hitler created a war. Maybe i can shine some light on the subject.
You must understand the end of ww1 before you can know what started ww2. Here is a quote from former zionist turned defector and whistleblower Benjamin Freedman- “The Zionists in Germany, who represented the Zionists from Eastern Europe, went to the British War Cabinet and — I am going to be brief because it’s a long story, but I have all the documents to prove any statement that I make — they said: “Look here. You can yet win this war. You don’t have to give up. You don’t have to accept the negotiated peace offered to you now by Germany. You can win this war if the United States will come in as your ally.” The United States was not in the war at that time. We were fresh; we were young; we were rich; we were powerful. They told England: “We will guarantee to bring the United States into the war as your ally, to fight with you on your side, if you will promise us Palestine after you win the war.” In other words, they made this deal: “We will get the United States into this war as your ally. The price you must pay is Palestine after you have won the war and defeated Germany, Austria-Hungary, and Turkey.”
Needless to say England didn’t have a right to promise Palestine to anyone. This crooked deal has caused so much death on our planet not only did this help create ww2, but will also be responsible for ww3 if people don’t wake up.
So despite the public being a largely against entering the war and germans being the largest ethnic group in america at the time, on April 6, 1917 the american people were forced into ww1 by Woodrow Wilson. The same president who swindled the american people with the federal reserve act of 1913, but that’s another topic.
Soon after on November 2, 1917, the British keep their end of the bargain with the Balfour Declaration. Which was a letter from the United Kingdom’s Foreign Secretary Arthur James Balfour to Baron Rothschild.
On November 11, 1918 ww1 ended. The Treaty of Versailles on 28 June 1919 and the Treaty of St. Germain on 20 September of the same year thoroughly humiliated the Germans.
The old Austrian Empire was balkanised without respect to its various cultures and nationalities. East Prussia was separated from Germany by a large area ceded to Poland. The Sudeten Germans were placed under Czech control. The coal mining area of the Saar Valley was to be administered for fifteen years by the League of Nations and then a plebiscite held. The corrupt Weimar Republic was forced upon the German nation and the middle classes were robbed of their savings by corrupt finance. There were millions of unemployed and the Sparticist Jewish revolutionary leaders Karl Leibknecht and Rosa Luxembourg were stirring up red revolution. So to sum it up, the crooked dealings of international zionist and the harsh terms of the treaty of versailles made ww2 inevitable before Hitler.
