Question: When did the US go to war with the country taekwondo originated from?

full_context: Document 1: United States in the Korean War: In response to North Korea's invasion into South Korea the United Nations convened to formulate a response. The U.N. demanded North Korea's immediate withdrawal and, when this was not met, United States Army General Douglas MacArthur was appointed supreme commander of U.N. forces. To halt the rapid progress of North Korean forces into the south Task Force Smith was deployed to the Korean front from Japan. Task Force Smith consisted of U.S. Army officers and regiments of the Army's 24th Infantry Division that were stationed in Japan as occupational forces. Unfortunately the 24th were under trained, poorly supplied, and outnumbered. The 24th offered very little resistance against the North Korean advance. American and South Korean troops were pushed south and in late July 1950 Task Force Smith was overrun in the city of Taejon. Troops from the Army's 25th Infantry Division were deployed to Taejon to establish a new line and pullout the decimated 24th I.D. This addition of combat troops did not stop the North Korean advance and both American and South Korean troops were pushed further south.
Document 2: 2002 FIFA World Cup: The 2002 FIFA World Cup was the 17th staging of the FIFA World Cup which took place from 31 May to 30 June 2002 in South Korea and Japan. This world cup set a number of precedents. It was the first World Cup to be held in Asia. No previous World Cup was held on a continent other than Europe or the Americas. It was also the first World Cup to be jointly hosted by more than one nation. Finally, this was the last event to use the golden goal rule. Brazil won the tournament for a record fifth time, winning the final against Germany 2 -- 0. The victory meant Brazil qualified for the 2005 FIFA Confederations Cup for the fifth time, representing the World. In the third place play - off match against South Korea, Turkey won 3 -- 2 taking third place in only their second ever FIFA World Cup finals. China PR, Ecuador, Senegal and Slovenia made their first appearances at the finals.
Document 3: South Korea: The martial art taekwondo originated in Korea. In the 1950s and 1960s, modern rules were standardized, with taekwondo becoming an official Olympic sport in 2000. Other Korean martial arts include Taekkyon, hapkido, Tang Soo Do, Kuk Sool Won, kumdo and subak.Football and baseball have traditionally been regarded as the most popular sports in Korea. Recent polling indicates that a majority, 41% of South Korean sports fans continue to self-identify as football fans, with baseball ranked 2nd at 25% of respondents. However, the polling did not indicate the extent to which respondents follow both sports. The national football team became the first team in the Asian Football Confederation to reach the FIFA World Cup semi-finals in the 2002 FIFA World Cup, jointly hosted by South Korea and Japan. The Korea Republic national team (as it is known) has qualified for every World Cup since Mexico 1986, and has broken out of the group stage twice: first in 2002, and again in 2010, when it was defeated by eventual semi-finalist Uruguay in the Round of 16. At the 2012 Summer Olympics, South Korea won the Bronze Medal for football.
Document 4: Won Kuk Lee: Won Kuk Lee was born on April 13, 1907 in Seoul, actual capital of South Korea, which was occupied by Japan and whose regimen regulated all of the population’s activities in the peninsula. It prohibited the practice or teachings of any martial arts, so those interested, had to go outside of Korea (either China or Japan) to learn the arts. Lee was interested in martial arts at a very early age, and he used to get together with the elders in his natal Seoul to listen to the old stories that narrated the practice of millennial Korean martial arts like the Taekkyeon.
Document 5: Asian nations at the FIFA World Cup: South Korea and Japan were selected as hosts by FIFA on 31 May 1996. Initially, South Korea, Japan and Mexico presented three rival bids. However, the two Asian countries agreed to unite their bids shortly before the decision was made, and they were chosen unanimously in preference to Mexico. This was the first (and so far the only) World Cup to be hosted by two countries. The 2002 World Cup was the tournament's 17th staging. It was also the first World Cup held in Asia, and the last in which the golden goal rule was utilized. South Korea and Japan, the co-hosts, qualified automatically, leaving 2.5 spots open for competition between 40 teams. Myanmar withdrew from the tournament after being placed in Group 2 but before any matches had been played, therefore reducing the group to three teams. Afghanistan, Bhutan, North Korea and Timor - Leste did not participate in the qualification process. Asia's two remaining automatic qualifying berths were taken by Saudi Arabia and China PR. Iran failed to become a third Asian representative in the World Cup after losing their AFC / UEFA playoff against the Republic of Ireland.
Document 6: Japan: Baseball is currently the most popular spectator sport in the country. Japan's top professional league, now known as Nippon Professional Baseball, was established in 1936 and is widely considered to be the highest level of professional baseball in the world outside of the North American Major Leagues. Since the establishment of the Japan Professional Football League in 1992, association football has also gained a wide following. Japan was a venue of the Intercontinental Cup from 1981 to 2004 and co-hosted the 2002 FIFA World Cup with South Korea. Japan has one of the most successful football teams in Asia, winning the Asian Cup four times. Also, Japan recently won the FIFA Women's World Cup in 2011. Golf is also popular in Japan, as are forms of auto racing like the Super GT series and Formula Nippon. The country has produced one NBA player, Yuta Tabuse.
Document 7: United States in the Korean War: The first battle the Americans entered in the Korean War was the Battle of Osan, where about four hundred strong landed in Pusan airport on the first of July. The American troops were sent off to Taejon the next morning where Major General John H. Church the head of U.S. field headquarters was confident in the US troop's strengths to push back the North Koreans. On July fifth the troops were finally put to the test when North Korean tanks crept towards Osan. The four hundred infantryman of the U.S. also called Task Force Smith opened fire on the North Koreans at 8: 16 am. Only four of the North Korean tanks were destroyed and twenty - nine kept moving forward breaking the US line. At the end of the battle only two more North Korean Tanks and two regiments of North Korean infantry were destroyed. The US had lost the battle, revealing that the mere sight of US troops would not reverse the military balance in Korea. By early August, the North Korean troops had pushed back the US and South Korean troops all the way to Naktong River, which is located about thirty miles from Pusan. The two weeks of fighting following this resulted in the most casualties of US troops than any other equivalent period of this war. However, during this time the US pushed supplies and personnel to Korea and by the end of July South Koreans and US troops outnumbered the North Koreans, although the North had pushed back the US and South by an amazing amount the North had suffered over fifty thousand casualties. Also because North Koreas supply lines were so lengthy and with the US in control of the water and air replenishing there losses were slow.

Document 9: Korean War: On 25 November at the Korean western front, the PVA 13th Army Group attacked and overran the ROK II Corps at the Battle of the Ch'ongch'on River, and then decimated the US 2nd Infantry Division on the UN forces' right flank. The UN Command retreated; the U.S. Eighth Army's retreat (the longest in US Army history) was made possible because of the Turkish Brigade's successful, but very costly, rear-guard delaying action near Kunuri that slowed the PVA attack for two days (27–29 November). On 27 November at the Korean eastern front, a U.S. 7th Infantry Division Regimental Combat Team (3,000 soldiers) and the U.S. 1st Marine Division (12,000–15,000 marines) were unprepared for the PVA 9th Army Group's three-pronged encirclement tactics at the Battle of Chosin Reservoir, but they managed to escape under Air Force and X Corps support fire—albeit with some 15,000 collective casualties.
Document 10: Battle of Taejon: The Battle of Taejon (14–21 July 1950) was an early battle of the Korean War, between American and North Korean forces. Forces of the United States Army attempted to defend the headquarters of the 24th Infantry Division. The 24th Infantry Division was overwhelmed by numerically superior forces of the Korean People's Army (KPA) at the major city and transportation hub of Taejon.

Document 12: Korean War: The Battle of Osan, the first significant American engagement of the Korean War, involved the 540-soldier Task Force Smith, which was a small forward element of the 24th Infantry Division which had been flown in from Japan. On 5 July 1950, Task Force Smith attacked the North Koreans at Osan but without weapons capable of destroying the North Koreans' tanks. They were unsuccessful; the result was 180 dead, wounded, or taken prisoner. The KPA progressed southwards, pushing back the US force at Pyongtaek, Chonan, and Chochiwon, forcing the 24th Division's retreat to Taejeon, which the KPA captured in the Battle of Taejon; the 24th Division suffered 3,602 dead and wounded and 2,962 captured, including the Division's Commander, Major General William F. Dean.
Document 13: Sport in Iran: Many sports in Iran are both traditional and modern. Tehran, for example, was the first city in West Asia to host the Asian Games in 1974, and continues to host and participate in major international sporting events to this day. Freestyle wrestling has been traditionally regarded as Iran's national sport, however today, football is the most popular sport in Iran. Because of economic sanctions, the annual government's budget for sport was about $80 million in 2010 or about $1 per person.
Document 14: Korean War: In the resulting Battle of Pusan Perimeter (August–September 1950), the U.S. Army withstood KPA attacks meant to capture the city at the Naktong Bulge, P'ohang-dong, and Taegu. The United States Air Force (USAF) interrupted KPA logistics with 40 daily ground support sorties that destroyed 32 bridges, halting most daytime road and rail traffic. KPA forces were forced to hide in tunnels by day and move only at night. To deny matériel to the KPA, the USAF destroyed logistics depots, petroleum refineries, and harbors, while the U.S. Navy air forces attacked transport hubs. Consequently, the over-extended KPA could not be supplied throughout the south. On 27 August, 67th Fighter Squadron aircraft mistakenly attacked facilities in Chinese territory and the Soviet Union called the UN Security Council's attention to China's complaint about the incident. The US proposed that a commission of India and Sweden determine what the US should pay in compensation but the Soviets vetoed the US proposal.
Document 15: Korean War: Meanwhile, U.S. garrisons in Japan continually dispatched soldiers and matériel to reinforce defenders in the Pusan Perimeter. Tank battalions deployed to Korea directly from the U.S. mainland from the port of San Francisco to the port of Pusan, the largest Korean port. By late August, the Pusan Perimeter had some 500 medium tanks battle-ready. In early September 1950, ROK Army and UN Command forces outnumbered the KPA 180,000 to 100,000 soldiers. The UN forces, once prepared, counterattacked and broke out of the Pusan Perimeter.
