Perhaps it is too early to reach any conclusion in this regard. Trump is perhaps using this opportunity to improve his approval ratings. He may not be interested in an all out war against the North Korea. I still believe he is a much better choice than Hillary Clinton.
If your logic is correct, then I would say that Trump is much better than Hillary. You are claiming that Trump is talking about the war, just to improve his approval ratings. That is still better than Hillary, who would have dropped nukes by now, if she was the POTUS.
