As I and others have noted elsewhere on numerous occasions, Rubio’s name-calling reveals the shallowness of his understanding of history and world politics. Defenders of the status quo can be counted on to shout the “isolationist” epithet whenever they want to discredit any challenges to it. Despite his relative youth, Rubio has adopted the foreign policy of men nearly twice his age. He seems blissfully unaware even of recent history. His campaign slogan calls for “A New American Century.” Sound familiar?
