Donald J. Trump is now threatening to wipe North Korea off the face of the planet because of “threats” the rogue nation is making toward the United States.

Have the North Koreans made any demonstrable moves against the world’s only super-duper power? Have they proved they are even capable of inflicting damage on this country? No.

They are threatening to do bad things. So that prompts the president of the United States to say he’ll bring unprecedented “fire and fury” to bear on North Korea, which has the ability now to deliver a nuclear weapon on board a missile.

As usual, the president isn’t thinking about what he is saying. He isn’t pondering how North Korea is going to respond to threats of maximum force. Oh, no. He’s simply popping off once again.

His statement delivered while on vacation has drawn some rebuke from military experts and from leading Republicans in Congress.

One of the critics is Sen. John McCain, R-Ariz., a man who knows combat and the consequence of war. “I don’t know what he’s saying and I’ve long ago given up trying to interpret what he says,” McCain said during an interview with a local Arizona radio station. “That kind of rhetoric, I’m not sure how it helps.”

It doesn’t.

McCain added: “In other words, the old walk softly but carry a big stick, Teddy Roosevelt’s saying, which I think is something that should’ve applied because all it’s going to do is bring us closer to a serious confrontation. I think this is very, very, very serious.”

A first-strike response against North Korea is going to prompt a major ground war on the Korean Peninsula. Is that what the president wants to occur? Of course not, but that is going to be the inevitable consequence.

Trump must be able to deliver on his tough talk. McCain and others are unsure he can and are mortified that he would say out loud that he would issue such a careless threat.

But … the president “tells it like it is.”
