"Finding no room for intellectual discussion in Rand’s sphere (and years later satirizing her in his embarrassingly juvenile and unpublished play Mozart Was a Red), Rothbard searched for other alliances. So while Buchanan was joining with Nixon, Rothbard was singing the praises of Tricky Dick’s archenemies: the New Left. Sometimes it was hard to tell if the anarchist Rothbard was simply looking for people to take him seriously, and at other times it was hard to tell how they could. For Rothbard, the way to freedom was to destroy the only thing that ever stood in its way: government. He praised the Black Power movement at first, seeing it as a useful opponent to the state (though spending little time writing about race per se, being an ultra-individualist). In 1967 Rothbard wrote that Che Guevara was “an heroic figure for our time” and “the living embodiment of the principle of Revolution.” In other words, my enemy’s enemy is my friend—a principle that the New Right struggles with to this day."
