the Arctic 1949: North Atlantic Treaty
World War II left the United States and the Soviet Union as the dominant powers in Europe. Relations between the two began to deteriorate almost immediately, especially after US concerns over the Soviet installment of Communist regimes in Eastern Europe prompted President Truman to embark on a policy of "containment" by aiding the non-Communist regimes which surrounded the Soviet bloc. As this new "Cold War" heated up, the US and its European allies signed the North Atlantic Treaty, formally creating the NATO alliance to counter any potential Soviet attack.

A small detachment of Soviet forces, carried by two mine trawlers from Petropavlovsk, landed on Iturup - largest of the southern islands in the Japanese territory of the Kuril Islands.

On 23 August, the Japanese garrison on the islands was ordered to surrender, although resistance continued in some areas until 4 September.
