This paper shows how the genocide of the Germans in Poland such as the Danzig and Broomberg Bloody Sunday played a role in causing the Second World War. It critically analyzes this dark episode of history prior to the Holocaust that was censored by many historians. It debates on the reasons that pushed Adolf Hitler (of Jewish descent) to trigger the Second World War by invading Poland. It also shows that Winston Churchill (of Jewish descent) was as dangerous as Adolf Hitler and could have prevented the Second World War and eventually the Holocaust. This paper also delves into the historical hypothesis: ‘Could Adolf Hitler have been different?’
