Richard Leopold in *The Growth of American Foreign Policy* dicussses the endgame of US-Japanese negotiations in 1941:
"Konoye's downfall edged the two nations closer to war, but with shooting having begun in the Atlantic, Roosevelt still tried to keep things quiet in the Pacific. He hoped "to baby the Japanese along" until the Philippines were adequately manned with B-17 bombers. The first nine arrived on September 12, 1941, but a second echelon of twenty-five did not touch down until November 6. In Washington, time was a precious commodity, but in Tokyo, Tojo was determined to break the deadlock, by diplomacy or force, before the end of the year. The weather was growing less suited to amphibious landings, and the oil reserves were dwindling. On November 5 an Imperial Conference agreed to wage war against the United States and Great Britain if the conversations in Washington failed to produce results by November 25. Before that date two proposals, A and B, would be offered. The former contained a broad settlement in line with the minimum objectives of September 6; the latter was a stopgap measure. Should both be declined, the Japanese would ask their Axis allies to enter the fray; but they were prepared to go it alone.
"Thanks to its breaking the Japanese diplomatic code, the American government learned at once of this deadline. Chief of Staff George C. Marshall and Chief of Naval Operations Harold R. Stark urged Roosevelt to play for time and on November 5, 1941, asked that "no ultimatum be delivered to Japan." They reminded him that Germany's defeat was the primary objective and argued against fighting in case the Japanese invaded Russia from Manchukuo, China from northern Indochina, or eastern Thailand from southern Indochina. They said war in Asia was justified only if the United States and its dependencies or certain areas essential to their security were attacked. Those areas were the British Empire and its mandates, the Dutch Indies, Thailand west of the hundredth meridian and south of the Kra Isthmus, Portuguese Timor, and French New Caledonia. Roosevelt endorsed this estimate but made no promise of any sort.
"A diplomatic impasse was reached at the end of November, 1941. When Hull quickly rejected Plan A as offering nothing new, Nomura — joined dramatically by a special envoy, Saburo Kurusu — pressed frantically for acceptance of Plan B before the revised deadline expired on November 29. Presented on November 20, Plan B ignored the Tripartite Pact. It bound both governments to forego further advances in Southeast Asia, to restore trade relations as they had been on July 25, and to cooperate in getting from the East Indies the resources each needed. The Japanese undertook to evacuate Indochina when a general peace was established; meanwhile they would withdraw from the southern sector. The United States was obliged to supply Japan with "a required quantity of oil" and to desist from actions prejudicial to terminating hostilities in China. The last meant no more diplomatic and economic support for Chiang Kai-shek.
"Hull dismissed Plan B as "preposterous." Not content with a curb on their southward drive, he insisted that the Japanese abandon their four-year campaign against China and all gains made at China's expense since 1931. To please Marshall and Stark, however, he drew up on November 25, 1941, a counteroffer, a three-month modus vivendi. It required Japan to get out of southern Indochina at once, to reduce its forces in northern Indochina, and to renounce expansion in any direction. In return, the United States would admit Japanese imports and allow limited exports in cotton and oil, the latter for civilian use only. Tojo probably would have balked at the oil item, but he never had the opportunity. From London a not fully informed Churchill warned against weakening Chiang's regime; from Manila came reports of troop movements which suggested Japan was not negotiating in good faith. Worried by charges of appeasement at home and cries of protest in Chungking, Hull reversed himself that evening and decided to answer Plan B in another way.
"His resulting ten-point note of November 26, 1941, proposed in effect to turn back the hands of the clock to September, 1931. It called for the complete evacuation of Indochina and its joint protection by the United States, Great Britain, Japan, China, Holland, and Thailand. These six nations, plus the Soviet Union, would also sign a nonaggression pact. As to China, Japan would have to withdraw all its troops — thereby forsaking Manchukuo — to deal only with Chiang — thereby deserting its puppets — and to join the United States in giving up extraterritorial rights. For its part, the American government would lift restrictions on Japanese trade, conclude a new commercial convention, and stabilize the dollar-yen rate. Nomura and Kurusu realized immediately that the men in Tokyo would not — indeed, could not — accept those terms..."

Hull's ten-point note was not an "ultimatum" as has sometimes been claimed--but it was for all practical purposes an admission that negotiations had failed, and that the next move was up to Japan (with the only real question being not whether she would attack but where). What if instead Hull had gone ahead with the three-month *modus vivendi*--and Japan had accepted? (Does the business about the oil being for civilian use only have to be a sticking point? After all, oil is fungible.) Obviously, it was not a permament solution, and no agreement on China was likely to be reached, certainly not in the next three months.
So let's say the three month *modus vivendi* does delay the Pacific War--by three months. Consequences? When I raised this question in soc.history.what-if years ago, Rich Rostrom suggested some:
"The postponement of the Pacific War would very likely allow the British/Commonwealth forces in North Africa to follow up the CRUSADER victories to completion - Tripoli falls in March 1942. OTL the pursuit in N Africa continued for about two months after Pearl Harbor, but by 2/42 forces were being diverted massively to SE Asia and the pursuit stalled. Give the B/C forces three months of sole focus on North Africa and two months after to follow up, and IMHO Rommel is finished.
"This has major knock-on effects for French North Africa; most likely the pro-Allied conspirators there take over in mid-summer, obviating TORCH. Where the Second Front, then? Sicily? Crete?
"The other big knock-on is Burma. The Japanese starting three months later, and possibly meeting more effective resistance in Malaya, may not be able to finish the Burma campaign before the monsoon rains hit, or may even be stopped at the eastern side of Burma.
"This would leave the Burma Road open, which makes it far easier to get aid to China, and perhaps even possible to deploy a corps or weak army of US troops there. Which could lead to major field defeats of the Japanese army in China."
