World leaders of all stripes have said essentially the same thing about North Korean dictator/madman/goofball Kim Jong Un.

He’s nuts, unpredictable, dangerous.

Now comes Donald J. Trump, the leading Republican candidate for president of the United States, to give Kim “credit” for the ruthless manner in which he disposes of his political enemies.

Does the GOP White House hopeful include the way Kim had his uncle executed? There were reports that he fed his uncle to starving dogs, which then, well . . .  you know.

I’ll repeat once again: Being the leader of the world’s greatest nation requires a certain understanding of diplomatic nuance. Trump keeps revealing that he has no concept — none, zero — of that notion.

He wants to “make America great again”? How is he going to do that? By offering ill-timed words of encouragement to dangerous despots like Kim Jong Un?
