Ok, time to turn the tables

Most everyone knows a bit about World War II. We're all taught the basics of how it started in school yet we often stop our study on the day that the Axis surrendered. Then we learn a bit about the Paris Peace Treaty of 1947 and skip straight to the division of Germany and the Berlin Wall.

Hostilities ended on September 2, 1945 when Japan finally was the last to surrender.

The USA didn't officially declare peace with Japan until 8 September 1951 when the San Francisco Peace Treaty, officially known as the Treaty of Peace with Japan was signed. The Soviet Union refused to sign the peace treaty so technically they still remained at war with Japan.

When did World War II finally and completely end?
