On the Cold War between the United States and Soviet Union

First of all, according to your logic, if the Cold War is a joke, then World War II is even more a joke! Imagine: during World War II, how much can the total economic output of Germany, Italy and Japan add up? Why do they dare to challenge the world?

Secondly, as you said, the Cold War is mainly a confrontation between two protagonists (countries). Even the difference between the two, no matter how big, is better than Germany in World & II. Meaning & The gap between Japan and the whole world is much smaller, right? ~~

Third, the point is that the Cold War between the former Soviet Union and the United States completely inherited the "legacy" of the czar. Russia was not a "lamp-saver" from the beginning (for China, the lesson was profound), so, in the final analysis, the Soviet Union did it because of its national nature.
