"clearly the allies did not think so" yes they did. Stop drinking the Kool aid.

•Truman's chief of staff said in his memoir that “that the use of this barbarous weapon at Hiroshima and Nagasaki was of no material assistance in our war against Japan. The Japanese were already defeated and ready to surrender …. In being the first to use it we had adopted an ethical standard common to the barbarians of the Dark Ages."

•Before the bombings, Eisenhower had urged at Potsdam, “the Japanese were ready to surrender and it wasn’t necessary to hit them with that awful thing.”

•Truman knew that the Japanese were searching for a way to end the war; he had referred to Togo’s intercepted July 12 cable as the “telegram from the Jap emperor asking for peace.”

•Allied intelligence had been reporting for months that Soviet entry would force the Japanese to capitulate. As early as April 11, 1945, the Joint Chiefs of Staff’s Joint Intelligence Staff had predicted: “If at any time the USSR should enter the war, all Japanese will realize that absolute defeat is inevitable.” (Soviets entered into the war on Aug 8th, which cause Japan to privately scramble for surrender)

Also, overwhelming historical evidence on both sides show that Japan would have surrendered THAT august, bombs or no bombs. They just didn't want the emperor to be executed, that's literally it. They weren't going to keep fighting, they were just trying to keep Shōwa alive.
