Question: Who led a successful Marxist revolution in the country that invaded and tried to take over the country with the best internet in the world?

<P0-S0> 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). <P0-S1> The war began on 25 June 1950 when North Korea invaded South Korea following a series of clashes along the border. <P0-S2> The United Nations, with the United States as the principal force, came to the aid of South Korea. <P0-S3> China came to the aid of North Korea, and the Soviet Union also gave some assistance to the North. <SEP> <P1-S0> after announcing a willingness to negotiate a withdrawal of soviet forces, the politburo changed its mind and moved to crush the revolution. <P1-S1> on 4 november, a large soviet force invaded budapest and other regions of the country. <P1-S2> the hungarian resistance continued until 10 november. <P1-S3> over 2,500 hungarians and 700 soviet troops were killed in the conflict, and 200,000 hungarians fled as refugees. <P1-S4> mass arrests and denunciations continued for months thereafter. <P1-S5> by january 1957, the new soviet - installed government had suppressed all public opposition. <P1-S6> these soviet actions, while strengthening control over the eastern bloc, alienated many western marxists, leading to splits and / or considerable losses of membership for communist parties in capitalist states. <SEP> <P2-S0> in his early years popper was impressed by marxism, whether of communists or socialists. <P2-S1> an event that happened in 1919 had a profound effect on him: during a riot, caused by the communists, the police shot several unarmed people, including some of popper's friends, when they tried to free party comrades from prison. <P2-S2> the riot had, in fact, been part of a plan by which leaders of the communist party with connections to béla kun tried to take power by a coup; popper did not know about this at that time. <P2-S3> however, he knew that the riot instigators were swayed by the marxist doctrine that class struggle would produce vastly more dead men than the inevitable revolution brought about as quickly as possible, and so had no scruples to put the life of the rioters at risk to achieve their selfish goal of becoming the future leaders of the working class. <P2-S4> this was the start of his later criticism of historicism. <P2-S5> popper began to reject marxist historicism, which he associated with questionable means, and later socialism, which he associated with placing equality before freedom (to the possible disadvantage of equality). <SEP> <P3-S0> Rank Country / Territory Avg. <P3-S1> connection speed (Mb / s) Relative speed - Global 5.6 5.6 South Korea 26.7 26.7 Sweden 19.1 19.1 Norway 18.8 18.8 Japan 17.4 17.4 5 Netherlands 17.0 17 6 Hong Kong 16.8 16.8 7 Latvia 16.7 16.7 8 Switzerland 16.7 16.7 9 Finland 16.6 16.6 10 Denmark 16.1 16.1 <SEP> <P4-S0> Alexandra Kim, a Korean who lived in Russia, is sometimes credited as the first Korean communist. <P4-S1> She had joined the Bolsheviks in 1916. <P4-S2> In 1917, Vladimir Lenin sent her to Siberia to mobilize Koreans there against the counter-revolutionary forces and the Allied Expeditionary Forces. <P4-S3> In Khabarovsk Kim was in charge of external affairs at the Far - Eastern Department of the Party. <P4-S4> There she met with Yi Dong - Wi, Kim Rip and other Korean independence fighters. <P4-S5> Together they founded the Korean People's Socialist Party, the first Korean communist party on June 28, 1918.
