Nationalism is a double-edged sword that inspires both national pride and arrogance, conceit, and self-aggrandizement. There are many politicians who like to incite nationalism, because the effect is fast and the effect is fierce, and once they taste the sweetness, it is very difficult to quit, and eventually they will be eaten by side effects. Hitler's Third Reich was a typical failure, and Germany was crippled and committed suicide himself.
To make nationalism fanatical, we must preach the best of our own nation. Hitler was well versed in this and introduced the Aryan theory of the best. How did Germany lose World War I? In order to round up the lie and pull another Jewish betrayal theory, they all blame the Jews for traitors. In this way, the Germans were both proud and hated the Jews to the bone. The mass base of support for the Holocaust was laid.
World War I and World War II were bloody, but the perpetrators of World War I were safely disembarked after losing the war and going into exile, while a group of Nazi leaders in Germany in World War II were hanged in Nuremberg, largely to liquidate their crimes of killing Jews. Wow, I never expected that.
Since it is the best, there is no reason not to be superior. So Germany put the expansion of living space on the agenda. The first was the unification of the German people, so Austria and the Sudetenland of Czechoslovakia, which were inhabited by German nationalities, were successively annexed. The German people were satisfied with this wave of chicken blood and praised Hitler as a millennium great. But how Hitler could see this little profit was only the beginning.
Another compulsory lesson for fanatical nationalists is that only the roar of cannons is the truth, and cannons do not have butter. Hitler's armaments finally made Germany strong, so he brazenly provoked World War II with the chicken blood masses. Originally intended to expand the living space, he was beaten by the Allies, one-fifth of the people died, a quarter of the country was lost, Hitler committed suicide, and Eva was buried. Looking at the current map of Germany, you will find that the capital Berlin is very close to the border, which is unreasonable. This is all because of the repeated defeats in World War I and World War II, and the evil result of the cession of the land. The so-called opposite is nothing more than this.
By inciting fanatical nationalism, Hitler's speed of political rise to power was dizzying, the atrocities of Nazism were jaw-dropping, and the roller coaster-like ups and downs of the Third Reich were lamentable. The past is not forgotten, the teacher of the future, but the biggest lesson of mankind is that it is difficult to learn from the lessons.
