If there's one sensible policy statement that Donald Trump has made until now, it's his stance on nuclear weapons. A few days ago, Trump told the New York Times, "If Japan had that nuclear threat, I'm not sure that would be a bad thing for us." Nor would it be so bad, he said, if South Korea and Saudi Arabia had nuclear weapons, too. Essentially, Trump is saying that nuclear proliferation is not a bad thing. I agree.
