Why do I feel that Russia’s military strength is no longer strong?

A country’s strength has three basic things: resources, talents and social system. And resources depend on the land area and geographical location. World War I and World War II were initiated by Germany, Italy, Austria and other countries. At that time, the talents of the three countries were first-rate. They almost succeeded in facing Britain, France and Russia. France was occupied twice, but failed in the end. It has to do with geographical location, the lack of depth in the territory, and the lack of resources. To be honest, no matter World War I or World War II, the pre-war Soviet Union had no advantages. It had abundant land, but it was not exploited enough, and it did not have as many talents as Britain and France, especially in World War II. At that time, the Greeks and Demons did not put Russia first, which also illustrates this point. After quickly occupying the Western European continent, they started a battle with the United Kingdom. Without the Soviet Union's containment in Poland, the United Kingdom would have only surrendered. Germany also had no strategic depth. They had to fight the Soviet Union and Britain on the second line. As a result, they had already reached Moscow. It can be seen that the Soviet Union was not very strong at that time, but the Soviet Union was deep. If the six western countries were lost, it would still be the west. If Dnieper was lost, there would still be Volga. Life depends on the country. The area dragged the Xi Mo army, and then there was a landing and subsequent counterattack. Without the Soviet Union, even if the United States entered the war, the outcome of World War II would have been rewritten. After World War II, the Soviet industrial economy was almost completely destroyed. This is why the Soviet Union sent troops to Northeast my country. Stalin sent troops to Northeast China not for socialism, but entirely for the sake of socialism. Japanese industrial facilities in Tohoku. But after World War II, it relied on these and powerful resources to quickly surpass Britain and France. Only to compete with the United States. Although the United States has successfully split the Soviet Union, it cannot completely suppress Russia. The dispute between Russia and Ukraine is only temporary. Ukraine will eventually realize that it is not worth the gain in terms of humanities and geography to be at odds with Russia. A wise man will emerge. After becoming the leader of Russia, Ukraine will return to the embrace of Russia earlier than Belarus. Russia does not care about the independence of Elali. The separation of the three countries from the Soviet Union is a good thing for Russia, not a bad thing. Although the three countries are old industrial and capitalist countries, they have insufficient land and population. During World War II, 70% to 80% of the men in the three countries died. Not fully recovered yet. In the future international competition, there will not be many countries without them, but after Ukraine and Belarus returned to Russia, another Soviet Union came back.
