Document 2: Korean War: The Korean War (in South Korean Hangul: 한국전쟁, Hanja: 韓國戰爭, Hanguk Jeonjaeng, "Korean War"; in North Korean Chosungul: 조국해방전쟁, Joguk Haebang Jeonjaeng, "Fatherland Liberation War"; 25 June 1950 – 27 July 1953)[a] was started when North Korea invaded South Korea. The United Nations, with United States as the principal force, came to aid of South Korea. China, along with assistance from Soviet Union, came to aid of North Korea. The war arose from the division of Korea at the end of World War II and from the global tensions of the Cold War that developed immediately afterwards.

Document 4: Imperialism: Trotsky, and others, believed that the revolution could only succeed in Russia as part of a world revolution. Lenin wrote extensively on the matter and famously declared that Imperialism was the highest stage of capitalism. However, after Lenin's death, Joseph Stalin established 'socialism in one country' for the Soviet Union, creating the model for subsequent inward looking Stalinist states and purging the early Internationalist elements. The internationalist tendencies of the early revolution would be abandoned until they returned in the framework of a client state in competition with the Americans during the Cold War. With the beginning of the new era, the after Stalin period called the "thaw", in the late 1950s, the new political leader Nikita Khrushchev put even more pressure on the Soviet-American relations starting a new wave of anti-imperialist propaganda. In his speech on the UN conference in 1960, he announced the continuation of the war on imperialism, stating that soon the people of different countries will come together and overthrow their imperialist leaders. Although the Soviet Union declared itself anti-imperialist, critics argue that it exhibited tendencies common to historic empires. Some scholars hold that the Soviet Union was a hybrid entity containing elements common to both multinational empires and nation states. It has also been argued that the USSR practiced colonialism as did other imperial powers and was carrying on the old Russian tradition of expansion and control. Mao Zedong once argued that the Soviet Union had itself become an imperialist power while maintaining a socialist façade. Moreover, the ideas of imperialism were widely spread in action on the higher levels of government. Non Russian Marxists within the Russian Federation and later the USSR, like Sultan Galiev and Vasyl Shakhrai, considered the Soviet Regime a renewed version of the Russian imperialism and colonialism.
Document 5: Korean War: Korea was ruled by Imperial Japan from 1910 until the closing days of World War II. In August 1945, the Soviet Union declared war on Imperial Japan, as a result of an agreement with the United States, and liberated Korea north of the 38th parallel. U.S. forces subsequently moved into the south. By 1948, as a product of the Cold War between the Soviet Union and the United States, Korea was split into two regions, with separate governments. Both claimed to be the legitimate government of all of Korea, and neither accepted the border as permanent. The conflict escalated into open warfare when North Korean forces -- supported by the Soviet Union and China -- moved into the south on 25 June 1950. On 27 June, the United Nations Security Council authorized the formation and dispatch of UN forces to Korea to repel what was recognized as a North Korean invasion. Twenty - one countries of the United Nations eventually contributed to the UN force, with the United States providing 88% of the UN's military personnel.
Document 6: Communism in Korea: Alexandra Kim, a Korean who lived in Russia, is sometimes credited as the first Korean communist. She had joined the Bolsheviks in 1916. In 1917, Vladimir Lenin sent her to Siberia to mobilize Koreans there against the counter-revolutionary forces and the Allied Expeditionary Forces. In Khabarovsk Kim was in charge of external affairs at the Far - Eastern Department of the Party. There she met with Yi Dong - Wi, Kim Rip and other Korean independence fighters. Together they founded the Korean People's Socialist Party, the first Korean communist party on June 28, 1918.
Document 7: Kim Jong-il: Soviet records show that Kim was born Yuri Irsenovich Kim () in 1941 in the village of Vyatskoye, near Khabarovsk, where his father, Kim Il-sung, commanded the 1st Battalion of the Soviet 88th Brigade, made up of Chinese and Korean exiles. Kim Jong-il's mother, Kim Jong-suk, was Kim Il-sung's first wife. Inside his family, he was nicknamed "Yura", while his younger brother Kim Man-il (born Alexander Irsenovich Kim) was nicknamed "Shura".
Document 8: Korean War: The Korean War (in South Korean Hangul: 한국전쟁; Hanja: 韓國戰爭; RR: Hanguk Jeonjaeng, ``Korean War ''; in North Korean Chosŏn'gŭl: 조국해방전쟁; Hancha: 祖國解放戰爭; MR: Choguk haebang chǒnjaeng,`` Fatherland Liberation War''; 25 June 1950 -- 27 July 1953) was a war between North Korea (with the support of China and the Soviet Union) and South Korea (with the principal support of the United States). The war began on 25 June 1950 when North Korea invaded South Korea following a series of clashes along the border. The United Nations, with the United States as the principal force, came to the aid of South Korea. China came to the aid of North Korea, and the Soviet Union also gave some assistance to the North.
Document 9: History of communism: At the start of the 20th century, the Russian Empire was an autocracy controlled by the Tsar, with millions of the country's largely agrarian population living in abject poverty, and the anti-communist historian Robert Service noted, ``poverty and oppression constituted the best soil for Marxism to grow in ''. The man responsible for largely introducing the ideology into the country was Georgi Plekhanov, although the movement itself was largely organised by a man known as Vladimir Lenin, who had for a time been exiled to a prison camp in Siberia by the Tsarist government for his beliefs. A Marxist group known as the Russian Social Democratic Labour Party was formed in the country, although it soon divided into two main factions: the Bolsheviks led by Lenin and the Mensheviks led by Julius Martov. In 1905, there was a revolution against the Tsar's rule, in which workers' councils known as`` soviets'' were formed in many parts of the country and the Tsar was forced to implement democratic reform, introducing an elected government, the Duma.
Document 10: South Korea: On June 25, 1950, North Korea invaded South Korea, sparking the Korean War, the Cold War's first major conflict, which continued until 1953. At the time, the Soviet Union had boycotted the United Nations (UN), thus forfeiting their veto rights. This allowed the UN to intervene in a civil war when it became apparent that the superior North Korean forces would unify the entire country. The Soviet Union and China backed North Korea, with the later participation of millions of Chinese troops. After an ebb and flow that saw both sides almost pushed to the brink of extinction, and massive losses among Korean civilians in both the north and the south, the war eventually reached a stalemate. The 1953 armistice, never signed by South Korea, split the peninsula along the demilitarized zone near the original demarcation line. No peace treaty was ever signed, resulting in the two countries remaining technically at war. Over 1.2 million people died during the Korean War.

Norway has been ranked the highest twelve times, Canada eight times, followed by Japan which has been ranked highest three times. Iceland has been ranked highest twice.
Document 13: Military history of the United States: The Korean War was a conflict between the United States and its United Nations allies and the communist powers under influence of the Soviet Union (also a UN member nation) and the People's Republic of China (which later also gained UN membership). The principal combatants were North and South Korea. Principal allies of South Korea included the United States, Canada, Australia, the United Kingdom, although many other nations sent troops under the aegis of the United Nations. Allies of North Korea included the People's Republic of China, which supplied military forces, and the Soviet Union, which supplied combat advisors and aircraft pilots, as well as arms, for the Chinese and North Korean troops.
Document 14: Vladimir Lenin: Born to a moderately prosperous middle-class family in Simbirsk, Lenin embraced revolutionary socialist politics following his brother's 1887 execution. Expelled from Kazan Imperial University for participating in protests against the Russian Empire's Tsarist government, he devoted the following years to a law degree. He moved to Saint Petersburg in 1893 and became a senior Marxist activist. In 1897, he was arrested for sedition and exiled to Shushenskoye for three years, where he married Nadezhda Krupskaya. After his exile, he moved to Western Europe, where he became a prominent theorist in the Marxist Russian Social Democratic Labour Party (RSDLP). In 1903, he took a key role in a RSDLP ideological split, leading the Bolshevik faction against Julius Martov's Mensheviks. Encouraging insurrection during Russia's failed Revolution of 1905, he later campaigned for the First World War to be transformed into a Europe-wide proletarian revolution, which as a Marxist he believed would cause the overthrow of capitalism and its replacement with socialism. After the 1917 February Revolution ousted the Tsar and established a Provisional Government, he returned to Russia to play a leading role in the October Revolution, in which the Bolsheviks overthrew the new regime.
Document 15: Communications in Somalia: As of 2009, dial up, wireless and satellite services were available. Dial up internet services in Somalia were among the fastest growing on the continent, with an annual landline growth rate of over 12.5%. The increase in usage was largely due to innovative policy initiatives adopted by the various Somali telecom operators, including free local in-town calls, a flat rate of $10 per month for unlimited calls, a low charge of $0.005 per minute for Internet connections, and a one-time connection fee of $50. Global Internet Company, a firm jointly owned by the major Somali telecommunication networks Hormuud Telecom, Telcom Somalia and Nationlink, was the country's largest ISP. It was at the time the only provider of dial up services in Somalia's south-central regions. In the northern Puntland and Somaliland regions, online networks offered internet dial up services to their own group of subscribers. Among these firms was Golis Telecom Somalia in the northeast and Telesom in the northwest.
