" The president and many of those who served him were sympathetic to the New Left interpretation of foreign affairs, one that considers so-called Western capitalist imperialism as the primary cause of the world’s problems. “We have history,” President Obama said. “We have history in Iran, we have history in Indonesia and Central America. So we have to be mindful of our history when we start talking about intervening, and understand the source of other people’s suspicions.” An underlying premise of the New Left interpretation of history is that an overly powerful America is more often a source of, rather than part of the solution to, the world’s problems.
