>Russia and Japan have never signed a peace treaty to formally end World War II.
Summary
At the Tehran Conference in November 1943, Joseph Stalin agreed that the Soviet Union would enter the war against Japan once Germany was defeated. At the Yalta Conference in February 1945, Stalin agreed to Allied pleas to enter World War II in the Pacific Theater within three months of the end of the war in Europe. On 26 July, the US, the UK, and China made the Potsdam Declaration, an ultimatum calling for the Japanese surrender that if ignored would lead to their "prompt and utter destruction".
The commencement of the invasion fell between the US atomic bombings of Hiroshima on 6 August and Nagasaki on 9 August. Although Stalin had been told virtually nothing of the US and UK's atomic bomb program by Allied governments, the date of the invasion was foreshadowed by the Yalta agreement, the date of the German surrender, and the fact that, on 3 August, Marshal Vasilevsky reported to Stalin that, if necessary, he could attack on the morning of 5 August. The timing was well-planned and enabled the Soviet Union to enter the Pacific Theater on the side of the Allies, as previously agreed, before the war's end.[20] The invasion of the second largest Japanese island of Hokkaido was originally planned by the Soviets to be part of the territory taken.[21]
At 11 pm Trans-Baikal time on 8 August 1945, Soviet foreign minister Vyacheslav Molotov informed Japanese ambassador Naotake Satō that the Soviet Union had declared war on Japan, and that from 9 August the Soviet Government would consider itself to be at war with Japan.[22] At one minute past midnight Trans-Baikal time on 9 August 1945, the Soviets commenced their invasion simultaneously on three fronts to the east, west and north of Manchuria. The operation was subdivided into smaller operational and tactical parts:
Khingan–Mukden Offensive Operation (9 August 1945 – 2 September 1945)
Harbin–Kirin Offensive Operation (9 August 1945 – 2 September 1945)
Sungari Offensive Operation (9 August 1945 – 2 September 1945)
and subsequently
Though the battle extended beyond the borders traditionally known as Manchuria – that is, the traditional lands of the Manchus – the coordinated and integrated invasions of Japan's northern territories has also been called the Battle of Manchuria.[23] Since 1983, the operation has sometimes been called Operation August Storm, after American Army historian Lieutenant-Colonel David Glantz used this title for a paper on the subject.[5] It has also been referred to by its Soviet name, the Manchurian Strategic Offensive Operation, but this name refers more to the Soviet invasion of Manchuria than to the whole war.
