Timber Glad my contention is welcome. Here is some evidence to support it.

JAPS ASKED PEACE IN JAN. ENVOYS ON WAY -- TOKYO
Roosevelt Ignored M'Arthur Report On Nip Proposals
By Walter Trohan
Release of all censorship restrictions in the United States makes it possible to report that the first Japanese peace bid was relayed to the White House seven months ago.
Two days before the late President Roosevelt left the last week in January for the Yalta conference with Prime Minister Churchill and Marshal Stalin he received a Japanese offer identical with the terms subsequently concluded by his successor, Harry S. Truman...

The authenticity of the Trohan article was never challenged by the White House or the State Department, and for very good reason. After General MacArthur returned from Korea in 1951, his neighbor in the Waldorf Towers, former President Herbert Hoover, took the Trohan article to General MacArthur and the latter confirmed its accuracy in every detail and without qualification.
US officials also knew that the key obstacle to ending the war was American insistence on "unconditional surrender," a demand that precluded any negotiations
America's leaders understood Japan's desperate position: the Japanese were willing to end the war on any terms, as long as the Emperor was not molested. If the US leadership had not insisted on unconditional surrender -- that is, if they had made clear a willingness to permit the Emperor to remain in place -- the Japanese very likely would have surrendered immediately, thus saving many thousands of lives.
the United States Strategic Bombing Survey (issued in 1946) stated in its official report: "Hiroshima and Nagasaki were chosen as targets because of their concentration of activities and population."
An editorial entitled "America's Atomic Atrocity" in the issue of August 29, 1945, told readers:
The atomic bomb was used at a time when Japan's navy was sunk, her air force virtually destroyed, her homeland surrounded, her supplies cut off, and our forces poised for the final stroke ... Our leaders seem not to have weighed the moral considerations involved. No sooner was the bomb ready than it was rushed to the front and dropped on two helpless cities ... The atomic bomb can fairly be said to have struck Christianity itself ... The churches of America must dissociate themselves and their faith from this inhuman and reckless act of the American Government.
Shortly after "V-J Day," the end of the Pacific war, Brig. General Bonnie Fellers summed up in a memo for General MacArthur: "Neither the atomic bombing nor the entry of the Soviet Union into the war forced Japan's unconditional surrender. She was defeated before either these events took place."
Navy Secretary James Forrestal termed the intercepted messages "real evidence of a Japanese desire to get out of the war." "With the interception of these messages," notes historian Alperovitz (p. 177), "there could no longer be any real doubt as to the Japanese intentions; the maneuvers were overt and explicit and, most of all, official acts.
Based on a detailed investigation of all the facts and supported by the testimony of the surviving Japanese leaders involved, it is the Survey's opinion that certainly prior to 31 December 1945 and in all probability prior to 1 November 1945 [the date of the planned American invasion], Japan would have surrendered even if the atomic bombs had not been dropped, even if Russia had not entered the war, and even if no invasion had been planned or contemplated.
General Douglas MacArthur, Commander of US Army forces in the Pacific, stated on numerous occasions before his death that the atomic bomb was completely unnecessary from a military point of view: "My staff was unanimous in believing that Japan was on the point of collapse and surrender."
General Curtis LeMay, who had pioneered precision bombing of Germany and Japan (and who later headed the Strategic Air Command and served as Air Force chief of staff), put it most succinctly: "The atomic bomb had nothing to do with the end of the war."

The skilled players, FDR, Truman and Secretary of War Henry L. Stimson tried out their new military "toy," as Barnes described the A-bomb, without a scintilla of justification.

Seems clear to me the war was prolonged to enable the atomic experiments to take place, and as soon as the bombs were dropped the war ended. Also please note there were two experiments, the first with a uranium gun-type device, the second, on Nagasaki with a plutonium implosion weapon. No doubt if there were other types that needed proving, that would have been done before the war was finally declared over.
