American foreign policy is in flux. Libertarian-minded conservatives are joining liberals in their critiques of military interventions, defense budgets and the surveillance practices of the National Security Agency. "Neo" conservatives like John McCain are lining up with liberals in denouncing libertarian conservatives as "isolationists." Liberals and conservatives alike are unhappy with the Obama Administration's tepid support for humanitarian interventions in Syria and its failure to advance human rights abroad -- normally touchstones of liberal internationalism. Are fundamental ideological changes in American foreign policy afoot?
