Sharon said that the United States failed to understand him. Also, the United States criticized the Israeli practice of assassinating Palestinians believed to be engaged in terrorism, which appeared to some Israelis to be inconsistent with the US policy of pursuing Osama bin Laden "dead or alive". In 2003, in the middle of the Second Intifada and a sharp economic downturn in Israel, the US provided Israel with $9 billion in conditional loan guarantees made available through 2011 and negotiated each year at the US–Israel Joint Economic Development Group. President Bush noted in an April 14, 2002, Memorandum which came to be called "the Bush Roadmap" (and which established the parameters for subsequent Israel-Palestinian negotiations) the need to take into account changed "realities on the ground, including already existing major Israeli population centers", as well as Israel's security concerns, asserting that "It is unrealistic to expect that the outcome of final status negotiations will be full and complete return to the armistice lines of 1949." He later emphasized that, within these parameters, details of the borders were subjects for negotiations between the parties. Bush had maintained a desire to resume the peace process in Israel, and had openly proclaimed his desire for a Palestinian state to be created before 2005. He outlined a road map for peace in cooperation with Russia, the European Union, and the United Nations, which featured compromises that had to be made by both sides before Palestinian statehood could become a reality. One particular proposal was his insistence on new Palestinian leadership; a stance that saw the appointment of the first ever Palestinian Prime Minister on April 29, 2003. Bush had denounced Palestine Liberation Organization leader Yasser Arafat for continued support of violence and militant groups. The road map for peace stalled within months after more violence and the resignation of the new Palestinian Prime Minister, Mahmoud Abbas. By the end of 2003, neither side had done what was outlined in the plan. In April 2004 Bush announced that he endorsed Israeli Prime Minister Ariel Sharon's plan to disengage from the Gaza Strip but retain Jewish settlements in the West Bank. He also announced agreement with Sharon's policy of denying the right of return. This led to condemnation from Palestinian President Yasser Arafat, Arab and European governments and was a major departure from previous U.S. foreign policy in the region.
