After the collapse of the Austro-Hungarian Empire, no matter what Austria's ideology is, whether it is liberal, conservative or fascist in power, as long as Germany pursues the expansion of Zhang Zhilu, it will inevitably slip into Germany's sphere of influence, which is the inevitable result of the geopolitical vacuum in Central and Eastern Europe and German nationalism.

The second result of the collapse of the Austro-Hungarian Empire was that revisionism was rampant before Hitler came to power and became the forerunner and response of Hitler's German expansionism.

In the Treaty of Trianon 1920, Hungary signed it on behalf of Austria-Hungary.

Hungary ceded Slovakia and Transcarpathian Ukraine to Czechoslovakia.

Transylvania and East Banat belong to Romania.

Croatia and western Banat belong to the Kingdom of Yugoslavia.

Almost from the signing of this treaty, Hungary became one of the most dissatisfied countries with the Versailles system, and also became the earliest and most active advocate of revisionism, even before Germany. Hungary's "contract revisionism" quarreled for a while in the 1920s-even worse than Germany's contract revisionism in territorial disputes, which almost led to war at that time.

Therefore, they are happy to see and really willing to help a country that destroyed the Versailles system stand up, as long as that country is willing to admit its territorial claims-and Nazi Germany did the same (1938, Hungary got a piece of territory as a reward. 1940, Hitler ordered Romania to hand over Transylvania to Hungary in order to repay Hungary's loyalty to the Axis Group.

At the same time, the Germans also got a country, Poland, which is not as good as Hungary in revisionism, but it is still valuable. During the two world wars, Poland's territorial expansionism and revisionism were very strong, and it always hoped to "recover lost land" and restore its ancient glory driven by nationalism.
