Question: How many years were there between Stalin's purge of military and community party and Khrushchev's speech to the Twentieth Party of Congress? Passage 1:The previous season was one of the worst for LSU under Les Miles, matching the record of the 2008 LSU Tigers football team. The team did manage to sign the consensus #2 recruiting class in the country, including top rated recruits Leonard Fournette, Malachi Dupre, and Brandon Harris, all who made contributions during the season. After the bowl game, Defensive Coordinator John Chavis announced he was leaving LSU for the same position at Texas A&M. LSU hired former Alabama defensive coordinator Kevin Steele to fill the position, and subsequently hired former Ole Miss head coach Ed Orgeron to coach the defensive line. Former defensive line coach and ace recruiter Brick Haley departed for the same position at Texas in February.
 Passage 2:Following the defeat of Royal Lao Army in the Battle of Luang Namtha in early May 1962 by People's Army of Vietnam and Pathet Lao forces, it appeared that a communist invasion of northern Thailand was imminent and on 15 May the Kennedy Administration ordered US combat forces into Thailand to deter any attack. On 18 May VMA-332 equipped with 20 A-4 Skyhawks deployed to Udorn from Naval Air Station Cubi Point in the Philippines and HMM-261 helicopters flew into the base. On 19 May detachments of Marine Air Control Squadrons 1 and 4 and Marine Air Base Squadron 12 were also flown into the base. On 19 May the command group of the 3rd Marine expeditionary brigade and the Battalion Landing Team 3rd Battalion, 9th Marines began flying in from Bangkok and then moved north to the town of Nong Khai. The Marines conducted field training exercises with the Royal Thai Army and civic action with Thai civilians while Naval Mobile Construction Battalion Ten which arrived in late May established a base camp and repaired public buildings. In late June HMM-162 replaced HMM-261. 
 Passage 3:On February 25, 1956, Khrushchev gave a clandestine speech to the Twentieth Party Congress of the Communist Party of the Soviet Union, which was entitled, "On the Cult of Personality and Its Consequences", which denounced Stalin and his protégés. Khrushchev charged Stalin with fostering a personality cult, despite maintaining support for the ideals of communism. The speech was highly critical of Stalin and his reign of terror, primarily denouncing the purges of the Soviet military and Communist Party, which had taken place during the latter part of the 1930s. The speech brought forth several accusations, notably those concerning the Moscow Trials, where rulings were made, based on forced confessions, which were obtained through torture. Judicial decisions were determined, based on liberal interpretations of Article 58 of the Russian SFSR Penal Code, which was introduced in 1927, in order to arrest individuals suspected of counter-revolutionary activities. Due process, in accordance with Soviet law, was often dismissed and replaced with summary proceedings issued by institutional commissions known as NKVD troikas, who issued sentences to the accused without representation, defense, or trial.
