Faster than you can say Crimea and almost as quickly as Russia invaded and annexed it, foreign policy has returned to the political radar. It never fully left, of course, as two wars, Arab Spring, Benghazi, Syria and more dominated the last decade.But when Russian President Vladimir Putin followed his Sochi success with the Crimean heist, suddenly questions around U.S. policy, action and reaction to our one-time Cold War foe became political.What options do western leaders have? What role should U.S. leaders play?
