The Clinton administration Middle East policy was heavily shaped by officials with close ties to Israel or to prominent pro-Israel organizations. The two most notable individuals were Martin Indyk and Dennis Ross.
Indyk was former deputy director of research at AIPAC. He cofounded the pro-Israel Washington Institute for Near East Policy. He served on Clinton National Security Council, as ambassador to Israel (1995 to 1997 and 2000 to 2001), and as assistant secretary of state (1997 to 2000).
Dennis Ross served as Clinton special envoy to the Middle East. He joined WINEP after leaving government in 2001.
Both were among President Clinton closest advisers at the Camp David summit in July 2000.
Indyk and Ross supported Oslo peace process and favored creation of a Palestinian state. But they did so only within limits of what would be acceptable to Israeli leaders.
The American delegation at Camp David took most of its cues from Israeli Prime Minister Ehud Barak. It coordinated negotiating positions with Israel in advance. It did not offer its own independent proposals for settling the conflict.
Even the Clinton parameters presented in December 2000 were less an independent American proposal. They were Clinton summary of where negotiations stood and his assessment of bargaining space within which a solution might be found.
Palestinian negotiators complained about this. Israelis would sometimes present them with a specific proposal. Later the Americans would offer the same idea. But Americans would label it a "bridging proposal." Another member of US team later admitted Israeli proposals were often "presented [to the Palestinians] as U.S. concepts, not Israeli ones." This subterfuge fooled no one and reinforced Palestinian suspicions.
Palestinian representatives protested that they were "negotiating with two Israeli teams—one displaying an Israeli flag, and one an American flag."
So the US negotiators served Israel position, not America own. They presented Israeli demands as American ideas to the Palestinians.
