The West Bank, including East Jerusalem, has been under military occupation by Israel since 7 June 1967, when Israeli forces captured the territory, then ruled by Jordan, during the Six-Day War. The West Bank is part of the state of Palestine, and its status as a militarily occupied territory has been affirmed by the International Court of Justice and, with the exception of East Jerusalem, by the Israeli Supreme Court. The West Bank, excepting East Jerusalem, is administered by the Israeli Civil Administration, a branch of the Israeli Ministry of Defense. Considered to be a classic example of an "intractable conflict", Israel's occupation is now the longest in modern history. Though its occupation is illegal, Israel has cited several reasons for retaining the West Bank within its ambit: historic rights stemming from the Balfour Declaration; security grounds, both internal and external; and the area's symbolic value for Jews.
Israel has controversially, and in contravention of international law, established numerous Jewish settlements throughout the West Bank. The United Nations Security Council has repeatedly affirmed that settlements in that territory are a "flagrant violation of international law", most recently in 2016 with United Nations Security Council Resolution 2334. The International Court of Justice has also found that the establishment of Israeli settlements is illegal under international law. The creation and ongoing expansion of the settlements have led to Israel's policies being criticized as an example of settler colonialism.
