The Geneva Conventions outline the responsibilities of an occupying power. Under the Fourth Geneva Convention, to which Israel is a party, states are prohibited from transferring civilians from the occupying power's territory into the occupied territory, and from creating permanent changes in the occupied territory that are not for the benefit of the occupied population.
There is broad international consensus that that all Israeli settlements in the West Bank – which includes East Jerusalem - violate the Fourth Geneva Convention and are, therefore, illegal according to international law. This position has been affirmed by the UN Security Council in Resolution 465, the International Court of Justice, the world's highest legal body, and by Amnesty International, Human Rights Watch, and the respected Israeli human rights organization, B'Tselem. Not only did the US government repeatedly affirm this position throughout the 1970s and 1980s, the Israeli Supreme Court has acknowledged de facto its validity by ruling that the West Bank and Gaza Strip are under "belligerent occupation."

A. The International Court of Justice, Legal Consequences of the Construction of a Wall in the Occupied Palestinian Territory
78. The territories situated between the Green Line (see paragraph 72 above) and the former eastern boundary of Palestine under the Mandate were occupied by Israel in 1967 during the armed conflict between Israel and Jordan. Under customary international law, these were therefore occupied territories in which Israel had the status of occupying Power. Subsequent events in these territories, as described in paragraphs 75 to 77 above, have done nothing to alter this situation. All these territories (including East Jerusalem) remain occupied territories and Israel has continued to have the status of occupying Power.
120. The Court concludes that the Israeli settlements in the Occupied Palestinian Territory (including East Jerusalem) have been established in breach of international law.
B. Human Rights Watch, Israel: Bush Should Lay Down the Law on Settlements, April 11, 2005
Israel's policy of encouraging, financing, establishing, and expanding Israeli settlements in the Occupied Palestinian Territories violates two main principles of international humanitarian law, or the laws of war. Under the Fourth Geneva Convention, to which Israel is a party, states are prohibited from transferring civilians from the occupying power's territory into the occupied territory, and from creating permanent changes in the occupied territory that are not for the benefit of the occupied population.
”Israel is not only violating international law in expanding its settlements, but also its commitments under the “road map” to freeze them,” said Whitson. “Israel must evacuate its settlements in the West Bank and East Jerusalem in order to uphold its responsibilities as an occupying power.”
C. Amnesty International, Israel/Occupied Territories, Removing Unlawful Settlements in the Occupied Territories: Time to Act, March 23, 2005
However, the evacuation of some 8,000 Israeli settlers from the Gaza Strip and from some very sparsely populated settlements in the West Bank must not be allowed to be used by Israel as an opportunity to expand other settlements in the West Bank, where some 400,000 Israelis live in violation of international law.
The international community has long recognized the unlawfulness of the Israeli settlements in the Occupied Territories. UN Security Council Resolution 465 (of 1 March 1980) called on Israel "... to dismantle the existing settlements and in particular to cease, on an urgent basis, the establishment, construction and planning of settlements in the Arab territories occupied since 1967, including Jerusalem".
However, the international community failed to take any measure to implement this resolution. Most Israeli settlements in the Occupied Territories were built after this resolution was passed, with the greatest expansion having taken place in the past decade. The establishment and expansion of settlements and related infrastructure in the West Bank is continuing on a daily basis, contrary to Israel's commitment under the UN-sponsored 2003 Roadmap peace plan. This week the Israeli government confirmed its plan to build 3,500 new settlement houses in the East Jerusalem area of the West Bank.
As well as violating international humanitarian law per se, the implementation of Israel's settlement policy in the Occupied Territories violates fundamental human rights provisions, including the prohibition of discrimination.
D. B'Tselem, Land Expropriation and Settlements
Since 1967, Israel has established in the West Bank (including East Jerusalem) and the Gaza Strip 152 settlements that have been recognized by the Interior Ministry. In addition, dozens of outposts of varying size have been established. Some of these outposts are settlements for all intents and purposes, but the Interior Ministry has not recognized them as such....
In that the very establishment of the settlements is illegal, and in light of the human rights violations resulting from the existence of the settlements, B’Tselem demands that Israel evacuate the settlements. The action must be done in a way that respects the settlers’ human rights, including the payment of compensation.
East Jerusalem, B'Tselem
East Jerusalem is occupied territory. Therefore, it is subject, as is the rest of the West Bank, to the provisions of international humanitarian law that relate to occupied territory. The annexation of East Jerusalem breaches international law, which prohibits unilateral annexation. For this reason, the international community, including the United States, does not recognize the annexation of East Jerusalem.
E. The United States Government
"Our position on settlements, I think, has been very consistent, very clear. The secretary expressed it not too long ago. He said settlement activity has severely undermined Palestinian trust and hope, preempts and prejudges the outcome of negotiations, and in doing so, cripples chances for real peace and prosperity. The U.S. has long opposed settlement activity and, consistent with the report of the Mitchell Committee, settlement activity must stop.” Mr. Richard Boucher, U.S. Department of State Daily Press Briefing -- November 25, 2002
"U.S. Policy toward the establishment of Israeli settlements in the occupied territories is unequivocal and has long been a matter of public record. We consider it to be contrary to international law and an impediment to the successful conclusion of the Middle East peace process, Article 49, paragraph 6, of the Fourth Geneva Convention is, in my judgment, and has been in judgment of each of the legal advisors of the State Department for many, many years, to be. . .that [settlements] are illegal and that [the Convention] applies to the territories.” Secretary of State Cyrus Vance before House Committee. on Foreign Affairs -- March 21, 1980
"Substantial resettlement of the Israeli civilian population in occupied territories, including East Jerusalem, is illegal under the convention and cannot be considered to have prejudged the outcome of future negotiations between the parties on the locations of the borders of states by the Middle East. Indeed, the presence of these settlements is seen by my government as an obstacle to the success of the negotiations for a just and final peace between Israel and its neighbors.” William Scranton, US Ambassador to the United Nations, UN Security Council -- March 23, 1976
F. The Israeli Supreme Court, as Cited by the PLO Negotiation Affairs Department
As early as 1979, the Israeli Supreme Court stated: “This is a situation of belligerency and the status of [Israel] with respect to the occupied territory is that of an Occupying Power.” In 2002, the Israeli Supreme Court held yet again that the West Bank and Gaza Strip “are subject to a belligerent occupation by the State of Israel.” In June, 2004, the Israeli Supreme Court reaffirmed that “since 1967, Israel has been holding [the West Bank] in belligerent occupation.”
