Adolf Hitler's "Mein Kampf" combines elements of autobiography with an exposition of his political ideology of Nazism, and outlines major ideas that later culminated in World War II. Especially evident in the book is the violent anti-Semitism of Hitler and his associates, drawing among other things on the Protocols of the Elders of Zion. For example, he claimed that the international language Esperanto was a Jewish plot, and presents arguments toward the old German nationalist idea of Drang nach Osten, the necessity to gain living space eastwards, particularly in Russia. .

             There are two passages that mention the use of poison gas: If at the beginning and during the First World War "twelve or fifteen thousand of these Hebrew corrupters of the .

             people had been held under poison gas, as happened to hundreds of thousands of our very best German workers in the field, the sacrifice of millions at the front would not have been in vain;" and again "These tactics are based on an accurate estimation of human weakness and must lead to success, with almost mathematical certainty, unless the other side also learns how to fight poison gas with poison gas.".

             Within this text, Hitler expresses his hatred toward the twin evils of the world, Communism and Judaism, and declares his aim to eradicate both from the earth. The new territory that Germany needed to obtain would nurture the German people, and explains why he invaded Eastern and Western Europe before he attacked Russia. He also announced that he intended to destroy German's parliamentary government, which he blamed for the ills against which he raged.

             Regarding foreign policy, Hitler declared that a National Socialist foreign policy would consist of several stages. In the first stage, by way of a massive re-armament program, Germany would overthrow the shackles of the Treaty of Versailles and form alliances with the British Empire and Fascist Italy.
