Question: Where did the arguer that Boris Lagutin's country of citizenship had become an imperialist power declare he would intervene in the Korean conflict?

Knowledge 1: Boris Lagutin
Boris Nikolayevich Lagutin () (born 24 June 1938 in Moscow) was possibly the most celebrated of Soviet boxers. During his career as a boxer, he has won 241 fights and lost only 11. He won medals in three Olympic Games, including two golds, in 1964 and 1968. Lagutin also won at European championships in 1961 and 1963 and at USSR championships in 1959, 1961–64 and 1968. Until 1967 Lagutin trained at VSS Trud, then - at VSS Spartak. During the period of failures, that followed the 1964 Olympics, Lagutin was removed from the USSR team roster. Along with his trainer Vladimir Trenin Lagutin managed to find causes of his losses and earned USSR and Olympic Champion titles again in 1968. [SEP] Knowledge 2: Korean War
On 27 June 1950, two days after the KPA invaded and three months before the Chinese entered the war, President Truman dispatched the United States Seventh Fleet to the Taiwan Strait, to prevent hostilities between the Nationalist Republic of China (Taiwan) and the People's Republic of China (PRC). On 4 August 1950, with the PRC invasion of Taiwan aborted, Mao Zedong reported to the Politburo that he would intervene in Korea when the People's Liberation Army's (PLA) Taiwan invasion force was reorganized into the PLA North East Frontier Force. China justified its entry into the war as a response to "American aggression in the guise of the UN". [SEP] Knowledge 3: 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.

A major consideration was the possible Soviet reaction in the event that the US intervened. The Truman administration was fretful that a war in Korea was a diversionary assault that would escalate to a general war in Europe once the United States committed in Korea. At the same time, "[t]here was no suggestion from anyone that the United Nations or the United States could back away from [the conflict]". Yugoslavia–a possible Soviet target because of the Tito-Stalin Split—was vital to the defense of Italy and Greece, and the country was first on the list of the National Security Council's post-North Korea invasion list of "chief danger spots". Truman believed if aggression went unchecked a chain reaction would be initiated that would marginalize the United Nations and encourage Communist aggression elsewhere. The UN Security Council approved the use of force to help the South Koreans and the US immediately began using what air and naval forces that were in the area to that end. The Administration still refrained from committing on the ground because some advisers believed the North Koreans could be stopped by air and naval power alone. [SEP] Knowledge 3: Declaration of war by the United States
The United States has formally declared war against foreign nations five separate times, each upon prior request by the President of the United States. Four of those five declarations came after hostilities had begun. James Madison reported that in the Federal Convention of 1787, the phrase ``make war ''was changed to`` declare war'' in order to leave to the Executive the power to repel sudden attacks but not to commence war without the explicit approval of Congress. Debate continues as to the legal extent of the President's authority in this regard. Public opposition to American involvement in foreign wars, particularly during the 1930s, was expressed as support for a Constitutional Amendment that would require a national referendum on a declaration of war. Several Constitutional Amendments, such as the Ludlow Amendment, have been proposed that would require a national referendum on a declaration of war.
