Question: 66 of the people whom the Soviets not want to engage in conflict were held hostage for 444 days in the late 1970s by a country. What is the presumed largest ethnic group of this country?

<P0-S0> in modern times, the javanese are the largest ethnic group in southeast asia, with more than 100 million people, mostly concentrated in java, indonesia. <P0-S1> in burma, the burmese account for more than two-thirds of the ethnic stock in this country, while ethnic thais and vietnamese account for about four-fifths of the respective populations of those countries. <P0-S2> indonesia is clearly dominated by the javanese and sundanese ethnic groups, while malaysia is split between half malays and one-quarter chinese. <P0-S3> within the philippines, the tagalog, cebuano, ilocano, and hiligaynon groups are significant. <SEP> <P1-S0> In April 1950, Stalin gave Kim permission to invade the South under the condition that Mao would agree to send reinforcements if they became needed. <P1-S1> Kim met with Mao in May 1950. <P1-S2> Mao was concerned that the Americans would intervene but agreed to support the North Korean invasion. <P1-S3> China desperately needed the economic and military aid promised by the Soviets. <P1-S4> At that time, the Chinese were in the process of demobilizing half of the PLA's 5.6 million soldiers. <P1-S5> However, Mao sent more ethnic Korean PLA veterans to Korea and promised to move an army closer to the Korean border. <P1-S6> Once Mao's commitment was secured, preparations for war accelerated. <P1-S7> Stalin made it clear that Soviet forces would not openly engage in combat, to avoid a direct war with the Americans. <SEP> <P2-S0> The CIA's World Factbook has estimated that around 79% of the population of Iran are a diverse Indo-European ethno-linguistic group that comprise the speakers of Iranian languages, with Persians constituting 53% of the population, Gilaks and Mazanderanis 7%, Kurds 10%, Lurs 6%, and Balochs 2%. <P2-S1> As with the spoken languages, the ethnic group composition also remains a point of debate, mainly regarding the largest and second largest ethnic groups, the Persians and Azerbaijanis, due to the lack of Iranian state censuses based on ethnicity. <P2-S2> Peoples of the other ethnicities in Iran make up the remaining 22%, with Azerbaijanis constituting 16%, Arabs 2%, Turkmens and Turkic tribes 2%, and others 2% (such as Armenians, Talysh, Georgians, Circassians, Assyrians). <SEP> <P3-S0> the iranian embassy siege took place from 30 april to 5 may 1980, after a group of six armed men stormed the iranian embassy in south kensington, london. <P3-S1> the gunmen, members of an iranian arab group campaigning for arab national sovereignty in the southern iranian region of khuzestan province, took 26 people hostage -- mostly embassy staff, but also several visitors as well as a police officer who had been guarding the embassy. <P3-S2> they demanded the release of arab prisoners from prisons in khuzestan and their own safe passage out of the united kingdom. <P3-S3> margaret thatcher's government quickly resolved that safe passage would not be granted, and a siege ensued. <P3-S4> over the following days, police negotiators secured the release of five hostages in exchange for minor concessions, such as the broadcasting of the hostage - takers' demands on british television. <SEP> <P4-S0> Fifty - two American diplomats and citizens were held hostage for 444 days from November 4, 1979, to January 20, 1981, after a group of Iranian college students belonging to the Muslim Student Followers of the Imam's Line, who supported the Iranian Revolution, took over the U.S. Embassy in Tehran. <P4-S1> It stands as the longest hostage crisis in recorded history. <P4-S2> The Iran hostage crisis was a diplomatic standoff between Iran and the United States of America.
