Charles Krauthammer, one of the highest-profile commentators of his generation, championed the muscular foreign policy of neoconservatism that helped lay the ideological groundwork for the 2003 invasion of Iraq. In addition to writing a syndicated column in The Washington Post, which garnered him a Pulitzer in 1987, he was an essayist for magazines across the political spectrum and a near-ubiquitous presence on cable news.
