Last March, in an interview with The New York Times, U.S. presidential candidate Donald Trump suggested it might not be a "bad thing" if Japan and South Korea developed nuclear weapons.
Really? In my view, this was a reckless suggestion, like so much else that Trump has proposed. He presents half-baked ideas while ignoring the negative consequences and sound advice on whatever subject he happens to be ricocheting off at the time.
Since becoming president, Trump hasn't broached the subject, but conservative pundit Charles Krauthammer thinks that North Korean actions warrant Japan playing the nuclear card.
