From his seat, beside the Japanese prime minister, it must have looked as though sumo, with its throwing, tripping and slapping, is a no-holds-barred endeavor, much like the Trump presidency.

But this is unfair to sumo. Sumo has a strict code of rules, in which the champion employs one of 82 kimarite, or winning moves. Use of illegal moves (kinjite), such as grabbing an opponent’s topknot or groin, or striking with a closed fist, brings disgrace on the fighter and, at the top level, national scandal.

To teach young wrestlers to avoid kinjite, the Japanese hold shokkiri – staged sumo matches in which the contestants poke eyes, pull hair, give wedgies and perform other fouls, all to comic effect.

Shokkiri, with its big, misbehaving men, is a bit like American professional wrestling. And it’s a whole lot like Trump’s trip to Japan: a series of fouls, deliberately performed.

• Pulling by the topknot: Japanese Prime Minister Shinzo Abe proclaimed that “North Korea launched short-range ballistic missiles” in defiance of the U.N. Security Council. But Trump, with Abe at his side, falsely declared, “There have been no ballistic missiles going out,” and said he’s “very happy with the way it’s going, and intelligent people agree with me.”

• Poke in the eye: Trump national security adviser John Bolton said there was “no doubt” North Korea violated U.N. resolutions. North Korea responded by calling Bolton a “war maniac” with an abnormal “mental structure” – and Trump sided with North Korea. “My people think it could have been a violation,” Trump said, in a Putin-Helsinki reprise. “I view it differently.” He called Kim Jong Un “very smart” and announced himself not bothered “personally” by the weapons tests.

• Punch in the solar plexus: After former Vice President Joe Biden called Kim a tyrant, North Korea called Biden a “fool of low I.Q.” – and Trump sided with the tyrant. Trump tweeted that he “smiled” when Kim “called Swampman Joe Biden a low IQ individual.” He later added, at a news conference with Abe, that Kim said “Biden is a low-IQ individual. He probably is, based on his record.”

• Kick to the head: Trump, on foreign soil, attacked “Sleepy” Biden for supporting the 1994 crime bill, a “dark period” because of its racist consequences. That occurred in essentially the same period Trump took out full-page ads urging the death penalty for the “Central Park Five,” who were later exonerated.

• Grabbing the groin: Trump, in his series of tweets overseas attacking domestic political opponents, put his Japanese hosts on the spot, saying they “told me that the Democrats would rather see the United States fail than see me or the Republican Party succeed – Death Wish!”

On this side of the Pacific, too, Trump and his appointees have been acting like shokkiri artists – committing fouls for entertainment.

Consider Housing and Urban Development senior official Lynne Patton, who planned Eric Trump’s wedding. After her boss, HUD Secretary Ben Carson, was mocked for confusing the term “real estate owned” (REO) with a cookie (Oreo) at a congressional hearing, Patton shared a social media message celebrating Carson’s genius while insulting Democratic New York Rep. Alexandria Ocasio-Cortez. Patton said her posting might violate federal ethics law, but “I honestly don’t care anymore.”

Transportation Secretary Elaine Chao, wife of Senate Majority Leader Mitch McConnell, R-Ky., failed to honor her promise to sell stock in a construction-materials company, The Wall Street Journal reported Monday. She made $40,000 by improperly holding the shares.

I honestly don’t care anymore.

Trump retweeted a mention of Rep. Liz Cheney, R-Wyo., saying actions by officials investigating Trump “could well be treason” – an offense punishable by death. Trump also gave Attorney General William Barr the authority to declassify intelligence material related to the Russia probe – a blow to intelligence agencies, allowing for selective release to besmirch federal agents.

I honestly don’t care anymore.

Trump’s treasury secretary, Steven Mnuchin, put off plans to honor anti-slavery legend Harriet Tubman on the $20 bill, saying the delay was needed to devote time to “counterfeiting issues.” And Trump’s secretary of state, Mike Pompeo, announced that Trump would use an emergency declaration to sell arms to Saudi Arabia, which Congress opposed.

I honestly don’t care anymore.

It’s too bad Trump didn’t pay closer attention during his visit to the sumo tournament. For then he might have learned that even the world’s most powerful men are losers if they don’t play by the rules.
