Yet he promised, and proved, to be a peace president. Obama will go down in history, above all, for peace, not for his clumsy efforts to expand social democracy. Uh, absence of American troops today is not peace. The world is a much less peaceful place today than it was six years ago. Putin's on the move, the Norks are gaining, and evil Islamists are freely slaughtering people in Iraq and Syria. That ain't peace.
Don't forget the Chinese missile developments and their blue-water navy. The Pax hallucinogenica won't last.
