Russia’s illegal occupation of the south Kuril Islands began on August 18, 1945, three days after Japan accepted the Potsdam Declaration (or the Proclamation Defining Terms for Japanese Surrender), which ended the Pacific War. Stalin’s Red Army nonetheless invaded the Chishima Islands, and has occupied them, Southern Karafuto (or Southern Sakhalin), and the islands of Etorofu, Kunashiri, Shikotan, and Habomai – which had never been part of the Russian Empire or the Soviet Union at any point in history – ever since.
