The United States won three wars (World War I, World War II and Cold War) because of good luck? Or is there another reason? Try to analyze

The reason why the United States did not participate in the war at the beginning of World War I was to do business with the warring parties and make a fortune in the war. In the later period of the war, due to the exhaustion of financial resources in various countries, it was far more profitable to take part in the war to snatch loot than to do business.

In World War II, the United States originally wanted to be like World War I, but I didn't expect Japan to be forced to pre-empt the war. However, America's wartime production capacity was extremely strong, coupled with its windfall in World War I, the Axis countries also made some mistakes in their strategic policies. As the history books say, the Axis countries are enemies of the world and will definitely lose.

During the Cold War, on the one hand, the Soviet Union developed too much heavy industry and agriculture. Get rid of it too slowly, and most experienced intellectuals will be eliminated, which is not good for the development of the country. During World War II, refugees from many countries fled there, some of which promoted the economic development of the United States, so the United States won ~ ~
