Donald Trump says Hillary Clinton’s proposed no-fly zones over Syria might trigger World War III. He could be right. Certainly there’s a real danger this new Cold War could turn hot as America and Europe push back against Russia’s increasingly aggressive diplomacy. NATO is stationing 4,000 troops along Russia’s historical buffer zone, the Baltics and eastern Poland, a real red flag for Russia. Trump says getting along with Russia wouldn’t be so bad, but how do you trust Putin when he continually lies about Russia’s operations in Ukraine and Syria? The next president will have to decide: détente or deterrence?
