Imbibing Randolph Bourne's idea that "war is the health of the state", Rothbard opposed all wars in his lifetime and engaged in anti-war activism. During the 1970s and 1980s, Rothbard was active in the Libertarian Party. He was frequently involved in the party's internal politics. He was one of the founders of the Cato Institute and "came up with the idea of naming this libertarian think tank after "Cato's Letters", a powerful series of British newspaper essays by John Trenchard and Thomas Gordon which played a decisive influence upon America's Founding Fathers in fomenting the Revolution". From 1978 to 1983, he was associated with the Libertarian Party Radical Caucus, allying himself with Justin Raimondo, Eric Garris and Williamson Evers. He opposed the "low-tax liberalism" espoused by 1980 Libertarian Party presidential candidate Ed Clark and Cato Institute president Edward H Crane III. According to Charles Burris, "Rothbard and Crane became bitter rivals after disputes emerging from the 1980 LP presidential campaign of Ed Clark carried over to strategic direction and management of Cato".
