The revision of 'Diktat' was clearly a fundamental goal of the Nazi's foreign policy. Hitler had made this clear from the Nazi Party's 25-Point Programme published in February 1920 which referenced things such as the 'union of all Germans in a Great Germany', a clear reference to Anschluss.
In Mein Kampf, written in 1925, Hitler declared Germans to be 'the highest species of humanity on this earth'. He wrote that 'only a sufficiently large space on this earth can ensure the independent existence of a nation'.
In October 1933, Germany withdrew from the Geneva Disarmament Conference and then from the League of Nations.
In January 1935 a referendum was organised in the Saar. Voters could decide to return to Germany or continue under League supervision. The Nazis used a combination of intimidation and violence to ensure a vote of more than 90% for a return to the Reich.
In March 1936, Hitler sent 20000 troops into the Rhineland. He used the principle of self-determination that had underpinned the TOV to legitimatise his demands that German speaking people be returned to the Reich.
Self-determination was his rationale for Anschluss in 1938 and the return of the Sudetenland from Czechoslovakia through the Munich Conference.
The state of Czechoslovakia itself had been created by the TOV, the German invasion of March 1939 represented a direct military challenge in the borders created after WW1.
The invasion of Poland in September 1939 was driven by the desire to remove the Polish Corridor, another creation of the TOV.
