The North Korean regime is extremely fiery, extremely insecure, sometimes hysterical. And when you're around somebody who's screaming and unstable, the last thing you want to do is add to the instability with your own unstable, hysterical rhetoric.

For the Democrats, they're trying to avoid having the Sanders-Clinton debate over and over again. But, to some degree, they're sentenced to that debate. Clinton is much more embracing of the global economy and the international world order. Sanders and Warren are much less so.
