The two-state solution has become a virtual dogma in Israeli–Palestinian official discussions: it was the basis of the Madrid Conference (1991), the Oslo Accords (1993), the Interim agreement (1995), the Hebron Protocol (1997), the Wye River Memorandum (1998), and so-called "Road Map" (2002). However, these agreements are rejected by various factions on the Palestinian side, most notably Hamas, Palestinian Islamic Jihad and the Popular Front for the Liberation of Palestine. The Oslo Accords were never fully adopted and implemented by both sides. After the Second Intifada in 2000, many believe that the two-state solution is increasingly losing its feasibility.
