The Israeli-Palestinian conflict is an ongoing dispute between Israel and Palestinians, beginning in the mid-20th century. It is one of the world's most enduring conflicts; the Israeli occupation of the West Bank and the Gaza Strip has lasted for 54 years. Various attempts have been made to resolve the conflict as part of the Israeli-Palestinian peace process, as well as efforts to reduce the broader Arab-Israeli conflict. Despite a long-term peace process, Israelis and Palestinians have failed to reach a final peace agreement. Progress was made towards a two-state solution with the 1993-1995 Oslo Accords, but today the Palestinians remain subject to Israeli military occupation in the Gaza Strip and in 165 islands across the West Bank.
