Beard had been criticized as an isolationist because of his views, but Beard in his writings referred to interventionists as isolationist. The views that he espoused in the final decade of his life were disputed by many contemporary historians and political scientists. However, some of the arguments in his "President Roosevelt and the Coming of the War" influenced "Wisconsin school" and New Left historians in the 1960s, such as William Appleman Williams, Gabriel Kolko, and James Weinstein. On the right, Beard's foreign policy views have become popular with "paleoconservatives" such as Pat Buchanan. Certain elements of his views, especially his advocacy of a non-interventionist foreign policy, have enjoyed a minor revival among a few scholars of liberty since 2001. For example, Andrew Bacevich, a diplomatic historian at Boston University, has cited Beardian skepticism towards armed overseas intervention as a starting point for a critique of US foreign policy after the Cold War in his "American Empire" (2004).
