In a 2008 column entitled "Charlie Gibson's Gaffe", Krauthammer elaborated on the changing meanings of the Bush Doctrine in light of Gibson's questioning of Republican vice-presidential candidate Sarah Palin regarding what exactly the Bush Doctrine was, which resulted in criticism of Palin's response. Krauthammer states that the phrase originally referred to "the unilateralism that characterized the pre-9/11 first year of the Bush administration," but elaborates, "There is no single meaning of the Bush doctrine. In fact, there have been four distinct meanings, each one succeeding another over the eight years of this administration." Krauthammer strongly opposed the Oslo accords and said that Palestinian Liberation Organization leader Yasir Arafat would use the foothold it gave him in the West Bank and the Gaza Strip to continue the war against Israel that he had ostensibly renounced in the Israel–Palestine Liberation Organization letters of recognition. In a July 2006 essay in "Time", Krauthammer wrote that the Israeli–Palestinian conflict was fundamentally defined by the Palestinians' unwillingness to accept compromise. During the 2006 Lebanon War, Krauthammer wrote a column, "Let Israel Win the War": "What other country, when attacked in an unprovoked aggression across a recognized international frontier, is then put on a countdown clock by the world, given a limited time window in which to fight back, regardless of whether it has restored its own security?" He later criticized Israeli prime minister Ehud Olmert's conduct, arguing that Olmert "has provided unsteady and uncertain leadership. Foolishly relying on air power alone, he denied his generals the ground offensive they wanted, only to reverse himself later." Krauthammer supported a two-state solution to the conflict. Unlike many conservatives, he supported Israel's Gaza withdrawal as a step toward rationalizing the frontiers between Israel and a future Palestinian state. He believed a security barrier between the two states' final borders will be an important element of any lasting peace. When Richard Goldstone retracted the claim 1 1/2 years after the issuance of the UN report on the 2008 Gaza war that Israel intentionally killed Palestinian civilians, including children, Krauthammer strongly criticized Goldstone, saying that "this weasel-y excuse-laden retraction is too little and too late" and called "the original report a blood libel ranking with the libels of the 19th century in which Jews were accused of ritually slaughtering children in order to use the blood in rituals." Krauthammer thought that Goldstone "should spend the rest of his life undoing the damage and changing and retracting that report."
