<P0-S0> harry s. truman (may 8, 1884 -- december 26, 1972) was an american statesman who served as the 33rd president of the united states (1945 -- 1953), taking the office upon the death of franklin d. roosevelt. <P0-S1> a world war i veteran, he assumed the presidency during the waning months of world war ii and the beginning of the cold war. <P0-S2> he is known for implementing the marshall plan to rebuild the economy of western europe, for the establishment of the truman doctrine and nato against soviet and chinese communism, and for intervening in the korean war. <P0-S3> in domestic affairs, he was a moderate democrat whose liberal proposals were a continuation of franklin roosevelt's new deal, but the conservative - dominated congress blocked most of them. <P0-S4> he used the veto power 180 times, more than any president since and saw 12 overridden by congress; only grover cleveland and franklin d. roosevelt used the veto so often and only gerald ford and andrew johnson saw so many veto overrides. <P0-S5> he is the only world leader to have used nuclear weapons in war. <P0-S6> he desegregated the u.s. armed forces, supported a newly independent israel and was a founder of the united nations. <SEP> <P1-S0> Raisa Maximovna Gorbacheva ( "Raisa Maksimovna Gorbachyova", , Титаренко; 5 January 1932 – 20 September 1999) was a Russian activist who was the wife of Soviet leader Mikhail Gorbachev. <P1-S1> She raised funds for the preservation of Russian cultural heritage, fostering of new talent, and treatment programs for children's blood cancer. <SEP> <P2-S0> 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. <P2-S1> 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 ''. <P2-S2> 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). <P2-S3> Europe was divided into a US - led Western Bloc and a Soviet - led Eastern Bloc. <P2-S4> Internationally, alliances with the two blocs gradually shifted, with some nations trying to stay out of the Cold War through the Non-Aligned Movement. <P2-S5> 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. <SEP> <P3-S0> The dissolution of the Soviet Union occurred on December 26, 1991, officially granting self - governing independence to the Republics of the Soviet Union. <P3-S1> On the previous day, 25 December 1991, Soviet President Mikhail Gorbachev, the eighth and final leader of the Soviet Union, resigned, declared his office extinct, and handed over its powers -- including control of the Soviet nuclear missile launching codes -- to Russian President Boris Yeltsin. <P3-S2> It was a result of the declaration number 142 - Н of the Supreme Soviet of the Soviet Union. <P3-S3> The declaration acknowledged the independence of the former Soviet republics and created the Commonwealth of Independent States (CIS), although five of the signatories ratified it much later or did not do so at all. <P3-S4> That evening at 7: 32 p.m., the Soviet flag was lowered from the Kremlin for the last time and replaced with the pre-revolutionary Russian flag. <SEP> <P4-S0> after about 300 years of partition by feudal dynasties, vietnam was again under one single authority in 1802 when gia long founded the nguyễn dynasty, but the country became a french protectorate after 1883 and under japanese occupation after 1940 during world war ii. <P4-S1> soon after japan surrendered on september 2, 1945, the việt minh in the august revolution entered hanoi, and the democratic republic of vietnam was proclaimed on september 2, 1945: a government for the entire country, replacing the nguyễn dynasty. <P4-S2> hồ chí minh became leader of the democratic republic of vietnam. <P4-S3> u.s. president franklin roosevelt had spoken against french rule in indochina, and u.s.a. was supportive of the viet minh at this time.
