Forget Pearl Harbor: Was America Considering Attacking Japan First?

Some thought it possible. 

The next morning, the Japanese attacked Pearl Harbor, rendering moot Roosevelt’s planned address. There would be no need to intervene in Great Britain’s behalf—it was now America’s war, as well. The entry in Henry Stimson’s diary that night summed up what leaders were thinking on both sides of the Atlantic. “When the news first came that Japan had attacked us,” Stimson wrote, “my first feeling was of relief —that indecision was over and that a crisis had come in a way which would unite all our people.” Pearl Harbor, not Malaya, had been the flashpoint.

This is a story of what might have been.

If Japan had chosen to attack far-off British Malaya on December 7, 1941, instead of Pearl Harbor, Hawaii, President Franklin Roosevelt was prepared to go before Congress and ask—for the first time in American history—for a declaration of war against a nation that had not fired the first shot against us. With the country solidly divided on the issue of getting involved in the war that was already raging in Europe, and with the president’s repeated promises not to send American boys to fight in a foreign war still ringing in congressional ears, the outcome of Roosevelt’s appeal was not preordained. Indeed, there is some reason to think that his appeal would have been rejected by an isolationist Congress, in which case the history of World War II would have been very different.

The circumstances surrounding FDR’s undelivered declaration began in August 1941, in obscure Argentia Harbor inside Placentia Bay, Newfoundland. There, four months before Pearl Harbor, Roosevelt and British Prime Minister Winston Churchill met secretly to thrash out the terms of what came to be called the Atlantic Charter. One of the primary objectives of the English-speaking leaders’ first summit was to come to some agreement regarding the increasingly aggressive and threatening moves the Japanese were making in the Far East. Churchill stressed the urgent need to make a joint declaration to the Japanese to either back off or face the consequences. Having barely escaped invasion by the Nazis a year earlier, the British had been forced out of Greece by the Germans in April, and now found themselves locked in a bitter struggle with General Erwin Rommel’s much-vaunted Afrika Korps in northern Africa. Spread desperately thin, the British were seeking a way to force the Japanese to reconsider attacking Malaya or the Dutch East Indies. That way, as Churchill understood, it was to have the United States agree to declare war on Japan if Malaya was attacked.

Japan’s Rising Threat

Following the fall of France in July 1940, a pro-Nazi government had been installed in Vichy in the southern part of the country. the Vichy government asserted control of all French colonies, including those in Indochina. As a signatory to the Tripartite Pact with Germany and Italy in September 1940, the Japanese immediately occupied eight strategically located air bases and the two major seaports in the region. In somewhat dilatory response, the United States, Great Britain, and the Netherlands notified Japan in July 1941 that unless it immediately withdrew its forces from Indochina, all trade would stop and an embargo on desperately needed oil would go into effect. In a meeting with Japanese Ambassador Kichisaburo Nomura in Washington, Roosevelt warned that if the Japanese attempted to seize oil-rich Borneo in the Netherlands East Indies, the Dutch and the British, who had committed to giving their Far East neighbors “all possible assistance,” would jointly declare war on Japan.

 

Churchill, for one, believed that Japan would be intimidated by the American warning. “It was evident that this was a stranglehold, and that the choice before them was either to reach agreement with the United States or go to war,” the doughty prime minister wrote. “The State Department in Washington believed, as I did, that Japan would probably recoil before the ultimately overwhelming might of the United States.” Unfortunately, Churchill was wrong. The Japanese chose to reject the Allied demands, complaining loudly that they were being subjected to “military, economic and political encirclement” by the three Allied countries and that the situation had become “intolerable.”

Realizing that war with Japan was on the horizon, Churchill focused on getting Roosevelt to formally announce his intention to declare war if the Japanese attacked the British or Dutch holdings in Indochina. Both men realized the difficulties the president would face in trying to get Congress, which had the sole power to declare war, to agree to fight on behalf of two European countries in far-off southeast Asia. Acknowledging that difficulty, Churchill wrote, “I must confess that in my mind the whole Japanese menace lay in a sinister twilight, compared to our other needs. My feeling was that if Japan attacked us the United States would come in. If it did not come in, we had no means of defending the Dutch East Indies, or indeed our own Empire in the East.”

 

Roosevelt’s Not-so-strong Statement to Japan

The House of Representatives’ razor-thin, one-vote decision to extend the Selective Service Act and continue a peacetime draft was a harbinger of just how difficult FDR’s selling job would be. Nevertheless, the British pressed hard for a strong statement from the president regarding the consequences of a Japanese attack on Malaya. Churchill telegraphed Foreign Secretary Anthony Eden on August 11 that he had gotten the “strong statement” from Roosevelt that he was after. “At the end of the note [he] will hand to the Japanese Ambassador,” cabled Churchill, “he will add the following passage, which is taken from my draft: Any further encroachment by Japan in the Southwest Pacific would produce a situation in which the United States Government would be compelled to take counter-measures, even though these might lead to war between the United States and Japan.”

As Churchill feared, the State Department was not convinced of the wisdom of such an overtly bellicose declaration. Once Secretary of State Cordell Hull got a look at the last paragraph of the draft, drawn up by Assistant Secretary of State Sumner Wells on his way back from the conference, Hull and his advisers agreed that the statement needed toning down. It was initially decided to replace the wording “such further steps may result in conflict between the two countries” with a more vague declaration that “the United States would take any and all steps of whatever character it may deem necessary in its own security.” After reading this over, however, Hull still found it too strong and worried that it “threatened war.”

In the final draft, which Roosevelt delivered to Ambassador Nomura on August 12, the document said only that “the government of the United States will take all steps toward safeguarding the legitimate rights and interest of the United States and American nationals and toward insuring the safety and security of the United States.” The next day, Roosevelt sent another Hull-drafted message to Churchill that cleverly avoided the contents of the toothless statement the president had just delivered to Nomura. Roosevelt’s message said, in part, “I made to him a statement along the lines of the proposed statement such as you and I had discussed. The statement I made to him was no less vigorous than and substantially similar to the statement we had discussed.” Although alarmed by the president’s watered-down statement, Churchill continued to hang on to the assurance Roosevelt had given him at the Atlantic conference that an aggressive Japanese move against the British or Dutch would bring America into the fight.

Playing for Time

Despite efforts on the diplomatic front to come to some agreeable answer to the embargo and the Indochina situation, no headway was made that summer or fall. On November 3, 1941, Churchill received a note from Chinese leader Chiang Kai-shek asking for British help in Malaya to stop an anticipated Japanese attack on Kunming to cut the Burma Road. Passing the information along to Roosevelt, Churchill somewhat disingenuously advised, “No independent action by ourselves will deter Japan, because we are so much tied up elsewhere. But of course we will stand with you and do our utmost to back you in whatever course you choose.”

On November 7, Roosevelt cabled back that he doubted such a Japanese land campaign was imminent. “We feel that continuing efforts to strengthen our defenses in the Philippines, paralleled by similar efforts by you in the Singapore area, will tend to increase Japan’s hesitation,” Roosevelt wrote. The president was still unsure what to do if Japan attacked the British and Dutch, but not the United States. Regarding that question, on the afternoon of November 17, he polled his Cabinet on whether they thought the American people “would back us up if we responded to such an attack with military action.” Responding with an overwhelming yes, the Cabinet agreed that Roosevelt should emphasize the increasingly critical situation in the press and in his speeches.
