Background: Charles Krauthammer (; born March 13, 1950) is an American syndicated columnist, author, political commentator, and former physician whose weekly column is syndicated to more than 400 publications worldwide. While in his first year studying at Harvard Medical School, Krauthammer became permanently paralyzed from the neck down after a diving accident, severing the spinal cord at C5. After spending 14 months recovering in a hospital, he returned to medical school, graduating to become a psychiatrist involved in the creation of the Diagnostic and Statistical Manual of Mental Disorders III, and later developing a career as a Pulitzer Prize-winning writer. He was a weekly panelist on PBS news program Inside Washington from 1990 until it ceased production in December 2013.
Context: Meg Greenfield, editorial page editor for The Washington Post who edited Krauthammer's columns for 15 years, called his weekly column "independent and hard to peg politically. It's a very tough column. There's no 'trendy' in it. You never know what is going to happen next." Hendrik Hertzberg, also a former colleague of Krauthammer while they worked at The New Republic in the 1980s, said that when the two first met in 1978, Krauthammer was "70 percent Mondale liberal, 30 percent 'Scoop Jackson Democrat,' that is, hard-line on Israel and relations with the Soviet Union"; in the mid-1980s, he was still "50-50: fairly liberal on economic and social questions but a full-bore foreign-policy neoconservative." Hertzberg now calls Krauthammer a "pretty solid 90-10 Republican." Krauthammer has been described by some as a conservative.  Krauthammer's major monograph on foreign policy, "Democratic Realism: An American Foreign Policy for a Unipolar World," is critical both of the neoconservative Bush doctrine for being too expansive and utopian, and of foreign policy "realism" for being too narrow and immoral; instead, he proposes an alternative he calls "Democratic Realism." In a 2005 speech (later published in Commentary Magazine) he called neoconservatism "a governing ideology whose time has come." He noted that the original "fathers of neoconservatism" were "former liberals or leftists."  More recently, they have been joined by "realists, newly mugged by reality" such as Condoleezza Rice, Richard Cheney, and George W. Bush, who "have given weight to neoconservatism, making it more diverse and, given the newcomers' past experience, more mature." In "Charlie Gibson's Gaffe" in The Washington Post, September 13, 2008, 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 refused to vote for Donald Trump, and believes there is evidence that the Trump campaign colluded with the Russian government.
