Evaluate the extent to which nations or groups used the memory of the First World War to advance their political objectives in the period 1918–1939. (I just need a thesis)

Hitler's Rise

Explanation:

The Nazi's used the apparent "disrespect" of nation of Germany in the Treaty of Versailles in their rise to power by explaining the starving peoples with an easy scapegoat in the Jews and the bad economic position the treaty put their nation in.

You could also say similar things with Italy, and Japan (Not getting the respect the felt they deserved). You could also do the USSR and the legacy of the Russian Revolution.
