After World War II, Germany was divided into two countries, namely East Germany and West Germany, but this was not in the interest of all Germans, in 1990, the two Germanys achieved reunification, and interestingly, the two major powers at that time, the Soviet Union and the United States, were supported, and Britain and Law were strongly opposed, especially Britain.
One reason why the Soviet Union did not prevent German reunification was that, historically, several great Russian emperors were Germans at all, such as Empress Catherine. There is also the Soviet Union, as the victorious power of World War II, took the opportunity to annex the birthplace of Germany, and now Kaliningrad, the Soviet Union is also afraid of Germany's future territorial claims, agreeing to the reunification of East and West Germany, which can be exchanged for this.
Moreover, at the time of German reunification, there was a provision in the Constitution that "no German territory outside the unified territory has not yet joined Germany", and Germany made great concessions in order to merge, including ceding some land to neighboring countries (Poland, Austria, France, etc.). Even so, Britain and France were still afraid of German reunification. This phrase, which the Germans declared to the world, made the Soviet Union willing to support German reunification.
The Soviet Union controlled East Germany for 45 years, until around 1990 the weak economy can no longer support the hegemony of Eastern Europe, West Germany also promised the Soviet Union a lot of conditions at that time, since the reunification of the two Germanys is inevitable, it is better to send a smooth water, to strengthen the future unification of Germany's Soviet-German relations, facts have proved that whether it is the Soviet Union from 1990 to 1992 or the disintegration of Russia, unified Germany also paid attention to the steady development of Soviet-Russian relations for a long time.
Geopolitically, The reunification of Germany is not good for them, because too close to the land area is also a reason, Britain's consistent style, Britain's diplomacy is to engage in continental balance, he does not want the European continent which country is strong, France is strong Britain united with other countries to engage in France, Germany is strong to unite other countries to engage in Germany, after the completion of their dismemberment into several small countries, this is the more europe fights the more small countries the reason. The United States and the Soviet Union could crush Germany no matter which country they were, and the atomic bomb had long been born, and another reason was that the United States and the Soviet Union wanted to contain Britain and France.
Britain's opposition reveals the typical European continental checks and balances theory, the unified Germany that pulled out the tiger's teeth can become an effective balancer of the European continent, the original British Empire likes to affect the European continent in this way, but the amazing combat effectiveness of Germany in the two world wars crushed the hegemony of the British Empire, so that Britain is unwilling to reproduce the opponent of this century, not to mention France, the northern territories of World War I are the hardest hit areas, and the Second World War was destroyed by Germany.
The real idea of England and France is that Germany would better be broken down into more than a hundred principalities, as it was more than a hundred years ago, and the real idea of the United States and the Soviet Union is that Europe can be dominated by you France alone, and you France would better be decomposed into more than a hundred principalities. I feel that Europe can not see the hope of reunification in a hundred years, the language, writing, culture and ethnicity are different, we are the same language and the same species, but the leaders of the Spring and Autumn Period are different, and the rapid development of the Zhou Gongfen seal is the result of occupying the main region. In the process of the merger of the two Germanys, the influence of foreign forces was only an objective external factor, and the main reason was that the people of East and West Germany were willing to unify and merge into a complete Germany.
