After the end of World War II, Japan was substantially occupied by the US military and completely reduced to a puppet regime of the United States. As of today, there are still tens of thousands of US troops stationed in Japan, and they have long been highly dependent on the United States politically and militarily, and national defense and security are all between the united States' thoughts.
Japan is a country with strong self-esteem and admiration for force, and it is undeniable that japan's ambitions have been suppressed to a certain extent because of the existence of the United States. So, once the "master-servant relationship" between the United States and Japan breaks down, who will Japan be the first to take revenge on the freed japan?

Since it is revenge, it is definitely necessary to find the biggest enemy of the vendetta. Then we may as well look at the history of Japan's development.
In 1853, Japan was in the first year of Kanaga. It was the United States that took the lead in using naval guns to blast open the door of Japan's "closed country" and dragged the otherwise stable Japan into the world tide, which is the famous "black ship incident" in Japanese history. Subsequently, Japan was forced to sign the unequal Japan-U.S. Goodwill Treaty with the United States. Later, Britain, France, Russia and other powers made business demands on Japan.
After that, Japan was fortunate to catch the fast track of Western development and become the only military power in Asia. In 1904, the Russo-Japanese War broke out, and Japan defeated its opponents in one fell swoop and completed a "cross-century revenge".
But in fact, what Japan hates most in its heart is the Western countries led by the United States. In the decades after the Meiji Restoration, although Japan developed with great success, countries such as britain and the United States have always had serious discrimination against Japan. After Japan mastered modern industrial technology, it began to invade neighboring countries and strengthen itself, and also hoped that its international status would be recognized by the first echelon such as Britain and the United States. However, in the eyes of Western countries, even if Japan becomes stronger, it is not "its own people". Even in 1920, the "anti-Japanese immigration policy" was introduced, which showed the psychology of exclusion. As the United States and European countries become more and more united, Japan's status and importance are getting lower and lower.
By the time of World War II, Japan's aggressive behavior was opposed by Britain and the United States. It also began to limit the supply of resources and weapons support to Japan. Later in the war, Japan understood that the United States would sooner or later break up with it, so it brazenly bombed Pearl Harbor in an attempt to severely damage the American fleet and prepare for the possible war that would break out next. Through this incident, we can also see that Japan's blind eyes will repay and say that they will do crazy personality.
Although Japan became the "servant" of the United States after the defeat of the war, its military development was quite limited, but it was also relatively sheltered from liquidation. Moreover, Japan has also laid an important military development foundation through the United States, including important technologies such as fighter jets and large surface ships. In the future, once the hegemonism of the United States cannot suppress Japan's militarist ambitions, in order to break free of the reins, the first thing Japan wants to drive away is the United States, and it is not impossible for the two sides to stand on the opposite side and then break out into a hot war.
