East Jerusalem
In the Palestine Liberation Organization (PLO)'s Palestinian Declaration of Independence of 1988, Jerusalem is stated to be the capital of the State of Palestine. In 2000, the Palestinian Authority passed a law proclaiming Jerusalem as its capital, and in October 2002, this law was approved by chairman Yasser Arafat. Since that time Israel has shut down all offices and NGO organisations connected to the PLO in East Jerusalem, saying that the Oslo Accords do not permit the Palestinian National Authority to operate in Jerusalem. The Organisation of Islamic Cooperation (OIC) recognised East Jerusalem as capital of the State of Palestine on 13 December 2017.
Hamas
On August 16, 2009, Hamas leader Khaled Mashal stated that the organization is ready to open dialogue with the Obama administration because its policies are much better than those of former U.S. president George W. Bush: "As long as there's a new language, we welcome it, but we want to see not only a change of language, but also a change of policies on the ground. We have said that we are prepared to cooperate with the US or any other international party that would enable the Palestinians to get rid of occupation." Despite this, an August 30, 2009 speech during a visit to Jordan in which Mashal expressed support for the Palestinian right of return was interpreted by David Pollock of the Washington Institute for Near East Policy as a sign that "Hamas has now clearly opted out of diplomacy." In an interview in May 2010, Mashal said that if a Palestinian state with real sovereignty was established under the conditions he set out, on the borders of 1967 with its capital Jerusalem and with the right of return, that will be the end of the Palestinian resistance, and then the nature of any subsequent ties with Israel would be decided democratically by the Palestinians. In July 2009, Khaled Mashal, Hamas's political bureau chief, stated Hamas's willingness to cooperate with a resolution to the Arab-Israeli conflict, which included a Palestinian state based on 1967 borders, provided that Palestinian refugees be given the right to return to Israel and that East Jerusalem be recognized as the new state's capital.
