President Donald Trump: the gift that keeps on giving — at least if you’ve got to write a weekly newspaper column.

Every week now there’s a new article highlighting the previous seven days as Trump’s “worst week ever.” One journalist pointed out that Trump has already served us up 10 of these worst weeks, most in the past few months.

Last week, of course, it was Trump’s statement that both sides of the Charlottesville riots were equally at fault.  

Equating neo-Nazis and Ku-Klux-Klanners with those opposing them: is that what our 45th president really believes? Or was he just tossing a few tasty morsels to his base? And, anyway, what’s worse: actually being a racist, or just promoting it?

“Unhinged” is no longer a rarely heard description of the man in the Oval Office.

And if Republican Congressmen have yet to turn their backs on him in droves, the process is clearly under way.  Once the focus turns to next year’s mid-term Congressional elections, it will surely accelerate.

But if his racist sympathies are bad enough, and indeed, potentially dangerous in our increasingly destabilized political scene, much more dangerous are his foreign policy views. North Korea is the most obvious snake-pit Trump is poking his stick in.  

One hopes the White House’s new chief-of-staff, John Kelly, a retired Marine Corps general, will manage to keep Trump and his security advisor, H.R. McMaster, another  ex-general, from launching what McMaster described in a recent televised interview as “a preventive war” against North Korea.  There is no such thing as a “preventive war’’ against a nuclear-armed country whose artillery alone could strike South Korea’s capital Seoul and its 25 million inhabitants.

North Korea isn’t the only threat out there. Looming on the horizon — placed there totally unnecessarily by Trump — is Iran: Trump has called the Iran nuclear deal “the single worst deal I’ve ever seen.”

He’s on record as telling the Wall Street Journal, a few days back, that “if it were up to me, I would have had them declared non-compliant 180 days ago.” And the Washington Post is now reporting that he’s getting some of his West Wing operatives to hype up a justification for backing out of the Iran deal.

If he actually does denounce it — despite the fact that Iran has been in compliance — Iran will quickly return to its nuclear track, followed no doubt by Saudi Arabia. Just what the Middle East, the world’s most unstable region, needs: the major state-backer of Sunni extremism and its Shia arch-enemy developing nuclear weapons. Trump is on a roll.

What his supporters fail to understand about Trump, even though he’s hardly hidden it: in his hey-day, the world’s “best deal-maker” fluctuated between successful high-risk deals and disastrous failed ones. And when the failed ones occasionally led to bankruptcy, he could always find a bank willing to bail him out.

Manhattan real estate transactions are not the best preparation for nuclear gamesmanship. You don’t want to be on the wrong end of the nuclear equivalent of bankruptcy — with no one around to bail you out.

But all is not gloom and doom: on Tuesday night, Trump was in his element once more, at a campaign-style rally in Phoenix, where he referred, though not by name, repeatedly and aggressively to his Arizona nemesis, Senator John McCain. The night before, in a prime-time televised, and tele-prompted, speech, we were fortunate to have the president bring us up to date on Afghanistan.  

Let me paraphrase his remarks: “I am delighted to have this opportunity to divert your attention from the racist opinions I expressed last week in my comments on the violence in Charlottesville.

“The ostensible purpose of my speech tonight is to let the American people know my plans for Afghanistan. As you know, this fall we will celebrate the 16th anniversary of our invasion of Afghanistan. During this time, we have had as many as 100,000 American troops, and as few, as is now the case, as 8,500. It doesn’t seem to matter how few, or how many, American soldiers we send there, we can’t win.

“But there’s good news I want to share with you: it is my intention, as it was of my predecessors, President Bush and President Obama, that we will not be defeated under my watch.

“My military advisors have not yet come up with a recommendation for what needs to be done to maintain the equilibrium, but they have assured me it will involve more American troops — who will continue to pave the way, as American soldiers have been doing for nearly 16 years, to victory.

“So I’m happy to be able to take this opportunity to assure you that however long I remain as president — indeed, even if I manage to serve out my full term — I guarantee you I will continue the Afghan War. And with any luck, when I step down, it will be entering its 20th year.’’

Another worst week ever.
