Hussein could not participate in the details of the talks, a task he handed to his brother Hassan. Hussein was referred to the Mayo Clinic in the United States after having urological problems; he had his left kidney removed after tests showed his ureter contained precancerous cells. When Hussein went back healed to Jordan, he received a hero's welcomea third of Jordan's population filled the streets to greet him. On 23 November 1992 he gave an unusually aggressive speech. He called on extremists on both the right and left of the political spectrum to end their opposition to the peace negotiations, denounced what he saw as the Gulf countries' undemocratic nature, and called on Saddam to introduce democracy to Iraq. Meanwhile, Yitzhak Rabin, under the leftist Labor Party, emerged as prime minister of Israel. Thus, the PLO and Israeli representatives were quick to reach an agreement, which culminated in the 1993 Oslo Accords. The Accords were held in secrecy between Arafat and Rabin without Hussein's knowledge, completely marginalizing Jordan and the Palestinian-Jordanian delegation in Washington.
