The PLO stands for Palestine Liberation Organization, which is an umbrella political organization formed in 1964 claiming to represent the worlds Palestinians. It was created to centralize the leadership of various Palestinian groups that previously had operated as clandestine resistance movements. The PLOs legislature, the Palestine National Council (PNC), was composed of members from the civilian population of various Palestinian communities, and its charter (the Palestine National Charter, or Covenant) set out the goals of the organization, which included the complete elimination of Israeli sovereignty in Palestine and the destruction of the State of Israel. The PLO has dealt with numerous tasks with regard to the life of the Palestinian people in their main communities and throughout the world through the establishment of several institutions in such realms as health, education, and social services. The PLO has been designated a terrorist organization by the United States in 1987, but in 1988, a presidential waiver was issued, which permitted contact with the organization.
