Yeah, but the analogy is apt. The Chinese dream of dominating East Asia when the U.S. bugs out. Problem is, if Japan remilitarizes, they will miss the stability the U.S. brought to the region. Note: next time the Japanese invade Manchuria, we are not going to lift a finger.
China fears Japan more than U.S. China sent out overture to Japan again in a last couple of days, to make up and improve mutual relations. Japan does not owe any money(T-bills) to China, and Japanese business are already moving out of China. Unlike U.S. corporations, Japanese corporations tend to work with its government regarding security matters.
