Cordell Hull a was American attorney, political leader and diplomat. He was the longest-serving longes U.S. Secretary of State (1933-1944), with a special interest in international organizations and received Nobel Peace Prize for contributions there; negotiated to avert World War Two in the Pacific.
He engaged in extensive negotiations, in 1941, with Japanese Ambassador Kichisaburo Nomura and other officials trying to find a formula to avert the war. American intelligence officers thought he was the best Japan could send, but the situation was beyond correction. Pacific Fleet intelligence officer Edwin Layton wrote "Nomura was one of the few senior Japanese officials I knew who had real affinity for and understanding of the United States. His appointment at this critical time was a signal of Tokyo's intent to calm American concern. If anyone could have done it, Nomura was the man."  Layton, however, considered Nomura naive in proposing ideas that his government, which would have been unacceptable to the Japanese military leadership. Nomura reported that there was special American sensitivity over French Indochina.
26 November meeting
Cordell Hull negotiated extensively with Nomura, trying to avoid war. A memorandum from Hull to the Japanese, became one of the key factors in the Japanese decision for war in 1941. Privy Council President Yoshimichi Hara, who referred to the memorandum reporting the 26 November meeting with Hull and the Japanese ambassadors, quoting it (emphasis added) as "the United States has demanded we withdraw troops from all of China." The actual English text read only "China". Hara asked for clarification, and Foreign Minister Togo said it was unclear if Manchuria had been separated. Throughout the Nomura-Hull talks, China and Manchuria had always been separated,a confusing explanation from Togo, no one at the conference assumed so. Hara concluded that war was preferable to accepting the American proposal because
If we were to give in [to the United States, then we would not only give up the fruits of the Sino-Japanese War, and the Russo-Japanese War, but also abandon the results of the Manchurian Incident. There is no way we could endure this....It is clear that the existence of our empire is threatened, that the great achievements of the Emperor Meiji would all come to naught, and that there is nothing else we can do.
