The main Huk forces retreated south into the jungles where they set up new camps and new headquarters. The Huks believed they were safe from the Philippine forces and would have time to rebuild. The Philippine army and the U.S. Battalion Combat Team (BCT) hunted the Huks into the jungles, once again forcing the rebels to relocate. Shortly after becoming Defense Minister in 1950, future Philippines president Ramon Magsaysay began a series of programs to undermine the popularity of the Huks nationally. The first program organized a Defense Corps, starting from 1950 and ending in 1955, to resettle Huks and their families. In 1954, in order to win more favor from the general populace, Magsaysay created the National Resettlement and Rehabilitation agency, which redistributed land to the peasants of the Philippines, as well as encouraging migration to the more rural areas of the country. By the time Magsaysay died in 1957, he had completely undermined the Huk movement, changing it from a strong movement with thousands of armed insurgents to a few hundred with little public support. On September 6, 1955, the United States and the Philippines signed the Laurel-Langley Agreement, which amended the Bell Trade Act. The Laurel-Langley Agreement reduced the dependency of the Filipino economy on the US economy and brought down tariffs. The United States could no longer control the ratio of the US money to Filipino money. As stated in a lecture at the University of the Philippines-Manila, Professor Roland G. Simbulan demonstrated that at this time the CIA was covertly sponsoring the Security Training Center on the outskirts of Manila as a, "countersubversion, counterguerilla and psychological warfare school." The CIA was worried that they and the Philippine government were losing control of the rural areas of the Philippines to the Huks and their perceived Communist ideology. Through this organization, CIA funds were funneled into the National Citizens' Movement for Free Elections (NAMFREL) community centers, the Philippine Action in Development, and through the Asia Foundation. Public service ads were made and broadcast during the height of global Soviet aggression and the country initiated a large scale anti-Communist campaign. Propaganda was produced depicting the hard and terrible life one would live under communist rule and how one would lose their autonomy as well as their religion and families. The US reinforced its interests by backing American businesses and American-funded organizations. The American government did this by funneling
