I'm inclined to agree with you.
What I'm afraid of is that if the discussions go south, we'll have to count on Kim Jung Un to be the one to keep them from spiraling out of hand. I'd rather not be dependent on that guy to keep the peace. But I have absolutely no confidence the Trumpster will be able to do so.
Remember, Hitler did great until he invaded Poland. And even though things didn't sour for him right away, that was the moment when he lost control of the situation.
