Marshall was convinced that “every individual moving to the Pacific should be indoctrinated with a firm determination to see [the invasion] through.” He put the number of troops required for the operation at 766,700. The invasion plan was as follows: (1) to have the Russians attack the Japanese occupying Manchuria in China; (2) to “vitalize the Chinese” with air support and supplies so they could handle the Japanese occupying other parts of their country; and (3) all of which would allow the Americans—with British aid—to go after mainland Japan.
