<P0-S0> Don Carlos Faith Jr. (August 26, 1918 – December 1, 1950) was an officer in the United States Army during the Korean War. <P0-S1>  He was posthumously awarded the Medal of Honor for his actions from November 27, through December 1, 1950. <P0-S2>  In 1976 LTC Faith was posthumously inducted into the U.S. Army Officer Candidate School Hall of Fame at Fort Benning, Georgia. <SEP> <P1-S0> Iran–North Korea relations (Korean: 이란-조선민주주의인민공화국 관계 ; Persian: روابط ایران و کره‌ی شمالی‎ ‎ ) are described as being positive by official news agencies of the two countries. <P1-S1>  Diplomatic relations picked up following the Iranian Revolution in 1979 and the establishment of an Islamic Republic. <P1-S2>  Iran and North Korea pledge cooperation in educational, scientific, and cultural spheres. <P1-S3>  Some media reports claim this cooperation extends to nuclear cooperation, though official U.S. government publications and academic studies have disputed this. <P1-S4>  The United States has been greatly concerned by North Korea's arms deals with Iran, which started during the 1980s with North Korea acting as a third party in arms deals between the Communist bloc and Iran, as well as selling domestically produced weapons to Iran, and North Korea continues selling missile to Iran. <P1-S5>  North Korea and Iran are the remaining two members of George W. Bush's "Axis of evil", which has led to many of the concerns regarding Iran–North Korea relations. <SEP> <P2-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). <P2-S1>  The war began on 25 June 1950 when North Korea invaded South Korea. <P2-S2>  The United Nations, with the United States as the principal force, came to the aid of South Korea. <P2-S3>  China came to the aid of North Korea, and the Soviet Union also gave some assistance to the North. <SEP> <P3-S0> The Workers' Party of Korea (WPK) is the founding and ruling political party of the Democratic People's Republic of Korea (North Korea), and the largest party represented in the Supreme People's Assembly. <P3-S1>  The WPK is the sole governing party of North Korea, although it coexists "de jure" with two other legal parties making up the Democratic Front for the Reunification of the Fatherland. <P3-S2>  It was founded in 1949 with the merger of the Workers' Party of North Korea and the Workers' Party of South Korea. <P3-S3>  The WPK also controls the world's 5th largest armed force – Korean People's Army. <P3-S4>  This political party (and all of the other parties in the DPRK) remains illegal in South Korea (officially the Republic of Korea) under South Korea's own National Security Act and is sanctioned by Australia, the European Union, the United Nations and the United States.
