How did Hitler feel about World War 1?

Hitler viewed World War I as a pivotal moment in his life and a catalyst for his nationalist beliefs. He served as a soldier and felt a deep sense of pride in Germany’s military efforts, but he was profoundly disillusioned by the war's outcome and the Treaty of Versailles, which he believed humiliated Germany. This resentment fueled his political ambitions and the rise of his extremist ideology, which ultimately led to World War II.
