It is not the point of surrendering, but more the point of being willing to massacre its own people in a costly war for both. Politicians are opportunists, especially in the Democratic world, including the USA. If they see some gain, or a preventing of loss of money, they are always willing to listen at least. Whatever the people want is not at issue here, as the mind of a people can be guided by politicians and media.
The point is what the USA would have done, if the Japanese offered them peace in exchange for a return of former US held territory, such as the bases Wake and Guam and/or the Phillippines, which had no other purpose for the Japanese, other than to keep away Allied Armed Forces. A demilitarized Pacific region was an option, where the USA would not deploy forces in the region, and neither would Japan, at least outside the territorial waters of the homelands. Japan had no whishes in the Pacific, as its interests lay in Asia. Such a thing could be tempting for opportunists in the US House and Senate and perhaps the White House.
On the other side, the US People could also be moved agains the own leadership, by suggesting the US Government was making warcrimes, by sending to death US citizens in a war, nobody wanted. The US Fascist party and perhaps the Communists, could be mobilized to create internal chaos in the USA, especailly by the Germans, who were still Allied to Japan. (German-American Citizens were not thought to be a threath, compared to the Japanese-Americans).
The US people did reply immediately after Pearl Harbor. The reply is that they wanted war. Enlistments sky rocketed immediately. Recruiting ofices were swamped the week following Pearl Harbor. The offices were open 24 hours to process the me that wanted to figt. Both of my grandfathers signed up immediately after Pearl Habor. One was turned away because he was too old.
This might be one time in US history where there could of been demonstrations if the US did not avenge Pear Harbor! We were stabbed in the back and were pissed.
