Why did Hitler need to seize the countries of the world?

Resources, natural and human, for Germany, and, in particular, the worthy place of the Germans in the world, national superiority, and, finally, revenge on Europe, and especially France, for the defeat in the First World War. Instead of distant colonies, Hitler occupied nearby territories and brought valuable resources to the Reich. Back in Mein Kampf, written in 24, Hitler mentioned that if you unite all Germans in one state, this will give a reason to occupy foreign territories in order to get resources for the nation.
