Question

why did hitler most likely believe germany had a right to invade other countries?
the treaty of versailles did not state that germany could not invade other countries.
the german economy relied on selling exports, and these nations were no longer purchasing them.
the third reich was a struggling government that needed to gain land.
the concept of nationalism meant keeping all germans together.

Explanation:

Hitler's extreme nationalism, which included the idea of pan - Germanism (uniting all ethnic Germans), was a major factor in his belief that Germany had a right to expand. The Treaty of Versailles did restrict Germany in many ways but not directly on the issue of invasion as a general statement, but this was not the main reason for his expansionist views. The German economy's export situation and the Third Reich's land - seeking due to government struggles were not the core justifications for the belief in the right to invade. Nationalism, especially in the form of uniting all Germans under one nation, was a key ideological driver for Hitler's aggressive actions.

Answer:

The concept of nationalism meant keeping all Germans together.
