What aid would China's leadership request if Japan backed away from Pearl Harbor?
Short answerArtillery first, then aircraft and tanks, to strengthen defensive positions and support attacks.
NotesIf Japan's retreat from the Pearl Harbor operation signaled weakness, Chiang Kai-shek would seek material that could immediately improve the land war. Artillery would come first because it could reinforce defensive positions against Japanese attacks. The same guns would also support Chinese counterattacks, making them useful across both sides of the operational problem. Aircraft and tanks remain desirable, but they follow the more immediate need for massed fire support.
