Why has Donald Trump transformed his foreign policy from isolationist to interventionist?
He doesn’t have some newfound curiosity in foreign affairs. Nor does he now deeply care about the global order. He’s shifted his focus for a different reason entirely: because his domestic agenda keeps getting stymied by checks and balances.
Unlike at home, Trump has few restraints on the global stage. He likes that environment much more.
He’s a bull who needs his China shop.
America’s domestic political system is resisting Trump more than many think. Sure, he’s gotten things done and caused lots of trouble. And to the victims of his abuses, the restraints on his power are far too weak.
But Trump’s domestic agenda has been muddled and underwhelming, especially for a president whose party controls Congress.
This is true even when the noise is screeching. Take DOGE, Trump’s partnership with Elon Musk. Remember how it was supposed to dramatically reduce federal spending?
For all its sound and fury, DOGE was largely negated by the very president who authorized it. About Trump's 2025 spending bill, Musk asked: “What’s the point of DOGE if the government’s just going to add $5 trillion more in debt?”
Moreover, while many Republicans slavishly acquiesce to Trump, not all of them do. Republican senators are rejecting his demand to end the filibuster. House Republicans are investigating the Epstein files.
The courts, for their part, rule against Trump regularly, including striking down his signature tariffs policy. His effort to undo birthright citizenship will likely soon meet the same fate.
State and local governments are likewise resisting Trump. Just look at California’s and Virginia’s broad gerrymanders in response to his (and his fellow Republicans’) election machinations.
The media–traditional and independent alike–have been fierce, notwithstanding Trump’s threats (and lawsuits). And the people in the streets, like in Minnesota, have made their voices heard.
Polling data suggests that Democrats will take the House in November. If they do, Trump will likely be impeached (again), and his legislative agenda will be in tatters.
Indeed, Trump has worthy opponents across American society thwarting his domestic ambitions.
Every single day.
But foreign policy, alas, is different. These checks don’t work internationally. A simple comparison illustrates the point: The same president who can’t get his political rival, Adam Schiff, indicted can unleash the might of America’s military on a whim.
Trump can largely do what he wants globally–including blowing up suspicious ships, taking out heads of state, invading sovereign nations, and threatening to end a civilization on social media.
It’s not supposed to work this way. The United States Constitution is ambiguous in numerous respects. But with declaring war, it’s clear: Article 1, Section 8 grants to Congress, not the president, “The power to declare war.”
“Only Congress can declare war,” Republican Senator Rand Paul said in March while protesting the Iran invasion. “That’s not my opinion. That's Article 1 of the Constitution … History will not be kind to a Congress that gave away its most solemn responsibility.”
As Trump's supporters emphasize, multiple presidents have initiated hostilities without congressional support. But numerous others have gone to Congress, as George W. Bush did in 2002 before the Iraq war.
One virtue of working with Congress before declaring war is that the public debate is more robust. Today, the American people are left to guess why Trump invaded Iran.
When he did so, without first seeking congressional authorization, he violated Article 1, Section 8 of the Constitution.
It’s that simple. Yet there was no practical way to stop him.
Congress moves far too slowly to block an aggressive commander-in-chief. And the courts can only do so much. Judges can force Trump to refund his tariffs, for example, but they can’t unwind the invasion of another country.
Ultimately, the person in the Oval Office is what matters most. As John Adams put it long ago, “We have no government armed with power capable of contending with human passions unbridled by morality … [which] would break the strongest cords of our Constitution as a whale goes through a net.”
Trump’s global ambitions flow from his domestic frustrations. The way to restrain him should be to follow the Constitution. That is, unfortunately, like trying to catch a whale with a fishing net.

U.S. President Donald Trump speaks during a campaign rally at Pinnacle Bank Expo Center on the Nebraska State Fairgrounds on October 05, 2026 in Grand Island, Nebraska.
The President Invited Iran to Bomb My Home
I was driving home to San Diego from Los Angeles on Monday night when I heard that the President of the United States had offered both cities up to Iran as bomb targets. At a rally in Nebraska, defending his war, Trump told the crowd, “let [Iran] take out Los Angeles, let ‘em take out San Diego.” It was, he said, “a very small price to pay.”
I was coming from a Bernie Sanders rally for Proposition 40, the one-time tax on California billionaires that would send 90% of its revenue to healthcare. We desperately need it to pass because, in order to give tax breaks to billionaires, Trump signed a law that will strip health coverage from 10 million Americans; this tax will make sure we can still cover Californians. Call me crazy, but I think taxing billionaires one time so we can make sure kids in California get to see a doctor is a very small price to pay. I also think that even if Trump were joking, it is indefensible to make jokes about the potential destruction of so many lives. Human life is never a small price to pay. Human life is priceless.
Plus, the reality is: here in San Diego, we’re already paying the price for Trump’s actions, and it’s not small at all. He has gutted FEMA, tried to kill climate resiliency programs, and destroyed public health standards, while his signature law is set to cut off health insurance and food support for hundreds of thousands of San Diegans. Like plenty of American cities, San Diego is already busy finding local solutions to respond to the problems this president has recklessly created.
Not to mention, at least 19 American service members have been killed in this war already. Human rights monitors have documented more than 3,600 dead in Iran by April alone. Here at home, gas is sitting just pennies below its all-time record. Taxpayers have already spent more than $45 billion on the war, while Trump’s oil and gas portfolio has grown by roughly $15.5 million this year alone. Of course anything is a “small price” to someone paying free.99 for this war, and profiting from it. Meanwhile, We the People are paying twice: first for the war, and then for the consequences of that war. But now he wants San Diego to pay a third time, flippantly offering us up to Iran.
It is worth noticing which cities he thought to name. Were San Diego and Los Angeles strategically chosen to signify something to his audience, or were they simply the first cities that came to mind as expendable places? Either way, the effect is to normalize—-and to gauge a crowd’s reaction to–the idea of massive violence in major California cities, suitable targets because of their perceived liberal lean. So what if Iran needs to bomb a little bit of America before the war can be over? Who cares, says Trump, if they target Los Angeles and San Diego?
By the way, why didn’t he offer up San Francisco, the free-love hippie-town MAGA loves to hate (and also my birthplace)? Could it be because that’s where the tech titans live? The same ones who joined Trump for Xi Jinping’s state dinner, a guest list worth a combined $2.4 trillion?
San Diego may have fewer billionaires, but it is home to more than 115,000 active-duty service members and 230,000 veterans. One in six active-duty sailors–in the entire Navy–is stationed here. So is one in four Marines. You cannot throw a rock in this county without hitting a military family: brats and spouses and veterans are among us. I got out of the Navy last year after ten years, and eight of those were here in San Diego. When Trump says “let ‘em take out San Diego,” he’s talking about the backbone of the United States military. He’s also talking about the people fighting his war.
San Diego has not been watching this war from the sidelines. Today, the USS Abraham Lincoln returns to North Island after an almost yearlong deployment to the Middle East that featured food shortages, broken toilets, and mold in the showers after 286 days at sea without a single port call. Eight sailors in the Lincoln’s strike group attempted suicide, but in August, when a reporter asked whether the deployment had gone on too long, Trump said “not nearly long enough.” Now he has told a crowd in Nebraska that we should let Iran take out the city those sailors call home. These are sociopathic sentiments.
Last week at Quantico, Pete Hegseth closed his address to the force by telling them, “President Trump has your back and so do I.” To the contrary, President Trump has put one of the biggest military towns in the country forward as a target for our adversaries. With friends like these, the “domestic” in “against all enemies, foreign and domestic” starts to sound a lot less hypothetical.
San Diego is home to Naval Air Station North Island, Naval Base San Diego, Naval Amphibious Base Coronado, the Point Loma submarine base, Camp Pendleton, and Miramar (and I have been permanently stationed at or trained at all of them). If Iran bombed San Diego and Los Angeles, aside from the devastating loss of life, it would cripple an immense share of our national security readiness.
And for what, exactly? Trump says the war is “essentially almost over with.” This is the same man who claimed in June 2025 that Iran’s nuclear program had been “obliterated,” then launched a war over it anyway on February 28. More than seven months later, he wants us to believe two things at once: that we’ve basically won, and that we might need to sacrifice an American city or two to finish winning. If the war is almost over, why does anybody need to take out San Diego?
I wonder if Trump’s endorsed candidate for California’s 48th District here in San Diego County will respond to these remarks. He recently said “no pain, no gain,” when referring to the gas prices San Diegans are paying. Jim Desmond, would you apply that same mindset if we were bombed? Or do you have the moral courage to stand up for the people you’re running to represent?
Last November, six Democratic members of Congress, all veterans, including Senator Mark Kelly, recorded a video reminding troops of their duty to disobey unlawful orders, restating the law that says so. Trump called it “SEDITIOUS BEHAVIOR, punishable by DEATH,” and then his Justice Department went looking for an indictment, which a grand jury refused. The president treated reading the law out loud to the troops as a capital offense, but then he himself invited a foreign enemy to destroy two American cities, possibly as a punchline. Is anyone calling the latter sedition? Who is demanding accountability?
Calling our lives a small price to pay affirms a moral bankruptcy, as well as an obvious dereliction of duty to the office he holds. While we can’t impeach him or invoke the 25th Amendment ourselves, we must stop being so quiet about what we’re paying already. We can make our voices heard by calling our representatives, writing op-eds, knocking doors, phone banking, and voting in defiance of the man who threatens the safety of our city. Ballots are already arriving in mailboxes. Vote, and vote yes on 40 (and no on 41 and 42).
Trump has been harming our cities for a while, but now he is inviting our military adversaries to join him in the harm. If we have any self-respect as Americans, we must not tolerate our leaders disregarding the dignity of lives in this way. We must fight for our home.
