full_context: Document 1: Dissolution of the Soviet Union: In a nationally televised speech early in the morning of December 25, 1991, Gorbachev resigned as president of the USSR – or, as he put it, "I hereby discontinue my activities at the post of President of the Union of Soviet Socialist Republics." He declared the office extinct, and all of its powers (such as control of the nuclear arsenal) were ceded to Yeltsin. A week earlier, Gorbachev had met with Yeltsin and accepted the fait accompli of the Soviet Union's dissolution. On the same day, the Supreme Soviet of the Russian SFSR adopted a statute to change Russia's legal name from "Russian Soviet Federative Socialist Republic" to "Russian Federation," showing that it was now a sovereign state.

Document 6: Division of Korea: At the Tehran Conference and the Yalta Conference, the Soviet Union promised to join its allies in the Pacific War in two to three months after victory in Europe. On August 8, 1945, three months to the day after the end of hostilities in Europe, and two days after the atomic bomb was dropped on Hiroshima, the Soviet Union declared war on Japan. Soviet troops advanced rapidly, and the US government became anxious that they would occupy the whole of Korea. On August 10, 1945 two young officers -- Dean Rusk and Charles Bonesteel -- were assigned to define an American occupation zone. Working on extremely short notice and completely unprepared, they used a National Geographic map to decide on the 38th parallel. They chose it because it divided the country approximately in half but would place the capital Seoul under American control. No experts on Korea were consulted. The two men were unaware that forty years before, Japan and pre-revolutionary Russia had discussed sharing Korea along the same parallel. Rusk later said that had he known, he ``almost surely ''would have chosen a different line. The division placed sixteen million Koreans in the American zone and nine million in the Soviet zone. To the surprise of the Americans, the Soviet Union immediately accepted the division. The agreement was incorporated into General Order No. 1 (approved on 17 August 1945) for the surrender of Japan.

Document 9: Aftermath of World War II: The Aftermath of World War II was the beginning of an era defined by the decline of all great powers except for the Soviet Union and the United States, and the simultaneous rise of two superpowers: the Soviet Union (USSR) and the United States of America (USA). Allies during World War II, the USA and the USSR became competitors on the world stage and engaged in the Cold War, so called because it never resulted in overt, declared hot war between the two powers but was instead characterized by espionage, political subversion and proxy wars. Western Europe and Japan were rebuilt through the American Marshall Plan whereas Central and Eastern Europe fell under the Soviet sphere of influence and eventually an ``Iron Curtain ''. Europe was divided into a US - led Western Bloc and a Soviet - led Eastern Bloc. Internationally, alliances with the two blocs gradually shifted, with some nations trying to stay out of the Cold War through the Non-Aligned Movement. The Cold War also saw a nuclear arms race between the two superpowers; part of the reason that the Cold War never became a`` hot'' war was that the Soviet Union and the United States had nuclear deterrents against each other, leading to a mutually assured destruction standoff.

Document 15: Soviet Union: With the rise of strong nationalist and separatist movements inside the union republics, Gorbachev tried to avert a dissolution of the Soviet Union in the post-Cold War era. A March 1991 referendum, boycotted by some republics, resulted in a majority of participating citizens voting in favor of preserving the union as a renewed federation. Gorbachev's power was greatly diminished after Russian President Boris Yeltsin played a high - profile role in facing down an abortive August 1991 coup d'état attempted by Communist Party hardliners. On 25 December 1991, Gorbachev resigned and the remaining twelve constituent republics emerged as independent post-Soviet states. The Russian Federation -- formerly the Russian SFSR -- assumed the Soviet Union's rights and obligations and is recognized as the successor state of the Soviet Union. In summing up the international ramifications of these events, Vladislav Zubok stated: ``The collapse of the Soviet empire was an event of epochal geopolitical, military, ideological and economic significance.
