"I do not see how the Japanese can hold out against this united front"

Henry L. Stimson's quote suggests that he believes the Japanese will not be able to endure the combined forces of the Allied powers. This is likely due to the reality that the Allies had a much bigger military existence in the Pacific theater of World War II. The United States, Great Britain, China, and the Soviet Union had all joined forces to fight against the Japanese, and Stimson likely believed that the large size and strength of the Allied forces would be excessive for the Japanese to deal with. Stimson's quote also reflects the confidence of the Allies in their capability to defeat the Japanese, and the belief that the war would be won in a reasonably short amount of time. Ultimately, Stimson's quote proved to be precise, as the Allies had the ability to beat the Japanese in 1945.
