First of all, Germany faced threats from the Soviet Union and Eastern Europe after World War II. After World War I and World War II, the established powers such as Europe, Britain and France were greatly weakened and gradually replaced by powerful countries. America didn't suffer much in World War II. After World War II, China's economic strength reached 70% of the capitalist world and became the overlord of the capitalist world.
As we all know, the two atomic bombs dropped by the United States on Hiroshima and Nagasaki in Japan during World War II accelerated Japan's surrender, and nuclear weapons also changed the form of modern warfare. However, in August 1949, the Soviet Union broke the nuclear monopoly position of the United States and gained more confidence against the United States. Germany, which survived in the cracks, undoubtedly put itself on the guillotine by resisting the Soviet Union militarily. Germany knows that military recovery is hopeless. In the face of the militarily powerful Soviet Union, Germany might as well act as a peace envoy to ease the relationship between the East and the West with a weak and atoning attitude, which will lead to military expenditure and enhance its international image.
There are so many neighboring countries that even in modern society, a country does not deal with the outside world, let alone get along with its neighbors. In this geographical situation, Germany must pay the price for its crimes. After deeply reflecting on Nazi history, Germany won the recognition and support of European countries and conducted in-depth cooperation. Germany and France are old enemies. Faced with the same interests, they can also eliminate hostility with a smile. They joined hands to form the six-nation European Coal and Steel Alliance, which is the predecessor of the European Union, and Germany is also the first in the European Union.
