How did japan contribute to its own defeat?

The United States reacted to the occupation of Indochina by freezing Japanese assets and embargoing oil. The Japanese now faced the choices of either withdrawing from Indochina, and possibly China, or seizing the sources of oil production in the Dutch East Indies. Negotiations with Washington were initiated by the second Konoe cabinet. Konoe was willing to withdraw from Indochina, and he sought a personal meeting with Roosevelt, hoping that any U.S. concessions or favours would strengthen his hand against the military. But the State Department refused to agree to such a meeting without prior Japanese concessions. Having failed in his negotiations, Konoe resigned in October 1941 and was immediately succeeded by his war minister, General Tōjō Hideki. Meanwhile, Secretary of State Hull rejected Japan’s “final offer”: Japan would withdraw from Indochina after China had come to terms in return for U.S. promises to resume oil shipments, cease aid to China, and unfreeze Japanese assets. With Japan’s decision for war made, the negotiators received instructions to continue to negotiate, but preparations for the opening strike against the U.S. fleet at Pearl Harbor were already in motion. Japan’s war aims were to establish a “new order in East Asia,” built on a “coprosperity” concept that placed Japan at the centre of an economic bloc consisting of Manchuria, Korea, and North China that would draw on the raw materials of the rich colonies of Southeast Asia, while inspiring these to friendship and alliance by destroying their previous masters. In practice, “East Asia for the Asiatics,” the slogan that headed the campaign, came to mean “East Asia for Japan.” And Pearl Harbor

the revolution instituted a short-lived roman republic.
