American conservatism exists, if I could put it in my own words, to clean up the messes created by the country’s dominant class of liberal elites. The Reagan Revolution wasn’t a proper “revolution” at all but a series of conservative repairs, chief among them reforming a crippling tax code and revivifying the American economy. The great triumph of neoconservatism in the 1970s and ’80s was not the formulation of some original philosophy but the demonstration that liberal policies had ruined our cities. Richard Nixon won the presidency in 1968 and again in 1972 not by vowing to remake the world but by vowing to clean up the havoc created by Lyndon Johnson when he tried to remake Southeast Asia. George W. Bush would draw on a form of liberal idealism when he incorporated the democracy agenda into an otherwise defensible foreign policy—a rare instance of conservatives experimenting with big ideas, and look where it got them.
