Yesterday’s big discussion topic was a N.Y. Times Magazine story, “How Hillary Clinton Became a Hawk,” by Mark Landler — a concise, well-researched examination of Hillary’s aggressive foreign policy views. It complements Oliver Stone’s 3.30 HuffPost piece about how Clinton’s instincts are “steeped in the traditional post-World War II, Atlanticist, NATO-domination of the universe.” Landler’s piece is adapted from his book, “Alter Egos: Hillary Clinton, Barack Obama and the Twilight Struggle Over American Power” (Random House).
