International statecraft is a nuanced endeavor, but it’s not an entirely complicated matter.

The best practitioners of it look forward and don’t bother looking back, let alone tossing stones at those who came before them in the high office they occupy.

Thus, Donald Trump’s statements today about the pending peace agreement between South and North Korea lacked a sense of nobility one might expect from the president of the United States.

Trump spoke to the media along with German Chancellor Angela Merkel. He spoke seriously about the handshake and the historic meeting that occurred overnight between North Korea’s Kim Jong Un and South Korea’s Moon Jae-in. The two men have agreed to strike a peace deal on the Korean Peninsula, ending the official state of war that has existed since the Korean War hostilities ended in 1953.

Then he did that thing that annoys the living daylights out of me. He kept referring to his presidential predecessors’ “mistakes” in dealing with the reclusive North Korean regime.

Holy crap, Mr. President! Enough, already!

I expect fully for Trump take full credit for the deal that awaits the two Koreas. That’s fine. He can take credit if he wishes. But the expected deal came together through a complicated network of international relationships.

I just want the president to look forward from here. Kim Jong Un and Moon Jae-in have taken a huge step toward a long-sought-after peace agreement. It was forged by the deaths of hundreds of thousands of men — roughly 50,000 of whom were Americans — who fought a war that ended in a stalemate.

There is no need — none at all — for the president to re-litigate how his predecessors sought in vain to achieve the noble goal of peace in Korea.

I awoke this morning to an absolute stunner of an announcement.

Kim Jong Un and Moon Jae-in — the presidents of North and South Korea, respectively — have agreed to actually end the Korean War.

End the war? Yes. The Korean War never officially ended with a peace treaty. They stopped the shooting in 1953 after an armistice was signed, ending three years of bloody conflict on the Korean Peninsula.

The Koreas has been functioning with a cease-fire in place. The Demilitarized Zone separating the countries is nothing of the kind: it is the most militarized piece of real estate on Earth.

So, where do we go from here?

Kim and Moon signed an agreement to end the war. The treaty signing will occur later this year, according to the document the men signed.

But there’s more. There now appears some serious movement toward discussions relating to the denuclearization of the peninsula. That’s right. Kim Jong Un has agreed, apparently, to enter serious talks to take down his country’s nuclear ambitions.

Now for a big question: Who gets the credit for this seemingly monumental event? I have a strong hunch that the president of the United States, Donald J. Trump, is going to claim all the credit for himself. He is likely to tell us his tough talk regarding “Little Rocket Man” has brought Kim to his senses.

Well, the president deserves some credit. He needs to share it with the People’s Republic of China, which quite likely also has persuaded Kim to end this ongoing conflict. North Korea has precisely one dependable ally on Earth. It is the PRC. Does anyone believe that Kim would do anything so significant without China signing off?

I am stunned today to hear the news that came out of Korea.

Let us all say a prayer that Kim Jong Un — who is as mercurial and unpredictable as Donald Trump — remains faithful to the signature he has affixed on a document pledging to end the Korean War.

Sixty-five years after the end of the bloodshed, it’s about time!
