Will America go to war against Iran? Let us ask Donald Trump, human Magic 8 Ball.

Sometimes, signs point to yes. “You may have to fight … We’re looking for a total, complete victory,” the president said in the Oval Office on Wednesday afternoon, sounding very much as though a U.S. attack was imminent.

At other times: Don’t count on it. In that same session, Trump said he was thinking about inviting Iranian leaders to the White House for negotiations: “We’ll see. I may do that.”

And most of the time? Reply hazy, try again.

So, asked CNN’s Kaitlan Collins in that very same Oval Office gathering, “does that mean you haven’t made a decision yet on what to do?”

“I have ideas as to what to do,” Trump replied, in the latest formulation of his “concept of a plan” approach, but “I like to make the final decision one second before it’s due.”

Confused? It is decidedly so.

Americans may be unsettled to know that Trump will make the grave decision about war and peace based on a spur-of-the-moment impulse — but his public pronouncements over the last week suggest he’s relying heavily on the counsel of his new national security adviser, General Whimsy.

After Israel launched airstrikes against Iran, Trump rushed to post: “The U.S. had nothing to do with the attack on Iran.” Two days later, he was claiming credit for the attack he had nothing to do with, posting that “we now have complete and total control of the skies over Iran.” He credited munitions from “the good ol’ USA” for Israel’s success. By Wednesday, he was suggesting he was the one who ordered the Israeli attack. (“I said, ‘Let’s go!’”)

Over the course of one 24-hour period this week, Trump managed to reverse himself on Iran — twice. Monday morning, at the Group of Seven in Canada, he said a nuclear deal with Iran was “achievable.”

About eight hours later, he warned all 9.7 million residents of Iran’s capital to “immediately evacuate Tehran!”

Then, asked the next day whether his evacuation warning meant imminent war, Trump replied: “No, not at all. I want people to be safe.”

Any questions?

To the extent there has been a chronology to Trump’s disordered pronouncements, it goes something like this:

In the first days after the attack, Trump posted that Iran had a “second chance” to negotiate, adding that Iran and Israel “will make a deal” and there are “many calls and meetings now taking place.”

But a couple of days later, Trump furiously denied French President Emmanuel Macron’s claim that there was a ceasefire offer on the table — “Emmanuel always gets it wrong” — and asserted that “I have not reached out to Iran for ‘Peace Talks’ in any way, shape or form.”

As the week went on, Trump turned increasingly bellicose, threatening that the U.S. knows “exactly where the so-called ‘Supreme Leader’ is hiding” and “our patience is wearing thin.” Then followed an all caps “UNCONDITIONAL SURRENDER!” on Tuesday afternoon.

But by Wednesday morning, Trump was again soothing, saying “nothing’s too late” and “nothing’s finished.”

He told reporters he had issued Iran “the ultimate ultimatum,” but, when asked what that involves, he replied, “Oh, I don’t want to say.”

And he helpfully summarized his thinking on attacking Iran as follows: “I may do it. I may not do it. I mean, nobody knows what I’m going to do.”

Not even Trump himself, apparently. On Thursday afternoon, he sent his press secretary out to say he’ll decide “within the next two weeks.”

In domestic affairs, too, the only constant is inconstancy. Last week, the Trump administration directed Immigration and Customs Enforcement to pull back from roundups of migrants in the agricultural and hospitality industries — abandoning a key part of his plan for mass deportations because business leaders had squawked. Instead, Trump “ordered” ICE to target migrants “in America’s largest cities, such as Los Angeles, Chicago and New York” which “are the core of the Democrat Power Center.” He made it even more clear that he was using the federal government to protect friends and punish opponents when he said that the people he wants to round up are in “blue cities, all Democrat-run cities.”

But MAGA influencers then howled about the Trump administration abandoning plans to deport farm, restaurant and hotel workers — and, three days after the new policy became public, it was rescinded.

It all might be called the run-it-up-the-flagpole style of executive decision-making. Perhaps that is why Trump erected two 88-foot flagpoles this week on the White House grounds.
