Germany, Italy and Japan are only three small countries, and countries around the world have been fighting for so long. What was the second world war?

At that time, the strongest country in Europe was actually Germany, while the strongest country in Asia was Japan. Germany has created the tactics of blitzkrieg, and planes and tanks are very powerful, especially tiger tanks. Japan's Zero Fighter and its battleships are also very powerful.

Neither the United States nor the Soviet Union was strong during World War II. Fortunately, the Soviet Union had a killer weapon-the cold weather, which finally drove the Germans back, otherwise the Soviet Union would basically be finished. Germany's ethnic cleansing policy forced Einstein to flee to the United States and promoted the development of the atomic bomb. So the United States also has a killer weapon.

1945 near the end of the war, the United States and the Soviet Union frantically poached German scientists to promote the future strength of the two countries.
