Current version: 

 Arafat was a controversial figure throughout his political career. Arafat's supporters viewed him as a freedom fighter who expressed and symbolized the national aspirations of the Palestinian people for forty years. Some opponents, particularly Israelis and their supporters, considered Arafat a terrorist, and some Palestinians accused him of corruption, or of making too many concessions to Israel in efforts to settle the Israeli-Palestinian conflict (see the Oslo Accords).
