WaPo (“Trump’s top general foresees acute risks in an attack on Iran“):

As the Trump administration weighs an attack on Iran, the Pentagon’s top general has cautioned President Donald Trump and other officials that shortfalls in critical munitions and a lack of support from allies will add significant risk to the operation and to U.S. personnel, according to people familiar with internal discussions.

Gen. Dan Caine, chairman of the Joint Chiefs of Staff, expressed his concerns at a White House meeting last week with Trump and his top aides, these people said, cautioning that any major operation against Iran will face challenges because the U.S. munitions stockpile has been significantly depleted by Washington’s ongoing defense of Israel and support for Ukraine. Caine’s remarks at the White House meeting have not been previously reported.

Separately, in Pentagon meetings this month, Caine also has raised concerns about the scale of any Iran campaign, its inherent complexity and the possibility of U.S. casualties, one person said. The general has said that any operation would be made all the more difficult by a lack of allied support, this person said, speaking like others on the condition of anonymity to discuss private conversations.

In a statement, Caine’s office said that in his role as the president’s top military adviser, the chairman “provides a range of military options, as well as secondary considerations and associated impacts and risks, to the civilian leaders who make America’s security decisions.” Caine, the statement adds, “provides these options confidentially.”

Caine is, in other words, carrying out his statutory duty, laid out in the Goldwater-Nichols Act of 1986, as the chief military advisor to the President and the National Security Council.

White House spokeswoman Anna Kelly said Trump listens to a “host of opinions on any given issue and decides based on what is best for U.S. national security.” She described Caine as a “talented and highly valued member of President Trump’s national security team.”

I think everything about that, except the basis of the decision, is correct.

Trump, after this article’s publication, posted on social media that it is “100% incorrect” that Caine is “against us going to War with Iran.” Trump said that the general would not like to see a military confrontation with Iran but that if it did happen, “it is his opinion that it will be something easily won.” The people who spoke to The Post about Caine’s thinking directly contradicted Trump’s optimistic characterization.

Alas, I don’t think any of that is true.

First, while a retired National Guard three-star would not have been my top choice for Chairman (indeed, I would have retained CQ Brown), he’s by all accounts a professional. Caine isn’t offering his opinion as to whether we should attack Iran. Rather, he’s providing military options and conveying the associated risks. And no one in his position would tell the Commander-in-Chief that such a war would be “easily won.” There’s a reason—several of them in fact—why none of the eight U.S. Presidents since the 1979 Revolution have gone beyond very limited military incursions into Iran despite our belligerent status.

The White House meeting on Tuesday included Vice President JD Vance, Secretary of State Marco Rubio, CIA Director John Ratcliffe, Defense Secretary Pete Hegseth and White House adviser Stephen Miller, one person told The Washington Post.

Caine’s views, reported earlier by Axios, are seen as highly credible by the administration because of the successful execution of two other major operations he has overseen: the assault on Iran’s nuclear sites in the summer and the January raid to capture Venezuelan President Nicolás Maduro. Caine, said one person familiar with his conversations, will support whatever decision the president makes, as he did with previous operations, and does not want to be seen as taking any option off the table.

A recent episode of the Ezra Klein show was titled, “Who Has the Power in Trump’s White House?” The short answer, not shockingly, is President Donald J. Trump. But Klein’s guests, Atlantic journalists Ashley Parker and Michael Scherer, do a credible job of explaining who has access to the President, who he takes seriously, and how he ultimately decides.

POTUS listens to Caine. Trump likes his confidence, sees him as loyal, and the success of MIDNIGHT HAMMER and ABSOLUTE RESOLVE has cemented the impression that he’s a winner. If he’s saying this has significant risk, it will give the President some pause.

Further, it’s pretty clear that Trump is leery of “forever wars.” He wants big, quick wins. So, if he’s convinced there’s a substantial risk of either getting bogged down in a messy fight or coming away with an L, he’ll change course.

I can’t imagine Steven Miller and most of the other major voices in the administration much care about Iran; their motivations are almost entirely domestic culture wars and the like. Caine is the biggest voice on military affairs, though Marco Rubio (who I would expect to be similarly cautious about an overly ambitious mission set) also has some sway. And Trump will also listen to his chief of staff, Susie Wiles, if she tells him that the risks will play out poorly with the public.

Still, the biggest takeaway is that, unlike the first Trump administration, there’s no one who is going to tell POTUS “No.” If he decides he wants to take a high-stakes gamble, they’ll rally around him and carry out the mission.

    There’s the rub. Trump surrounded himself with sycophants, ideologues, power hungry asshats and grifters…his kind of people. They feed his childish fantasies…none of them give a damn about what’s right or good for the country. Nor do any of them know, or care, what comes the day after Trump does something stupid.

    The day after, El Taco usually blames the bad outcome on someone else.

    Trump insiders appear to be running a briefing campaign against the president’s Iran war plans—and they are not being subtle about it.

    Over roughly 48 hours beginning Sunday, at least five major news outlets each received strikingly similar tip-offs from anonymous U.S. officials warning that a major military operation against Iran would carry grave risks.

    As the Daily Beast reported on Monday, Trump’s indecision over whether to bomb Iran is sending the Pentagon into meltdown.

    Trump’s flip-flopping appears to have led officials to begin issuing ominous briefings against an Iran strike on Sunday, when the New York Times reported that the president, 79, was weighing a limited strike “in the coming days,” citing officials and sources familiar with the administration’s internal deliberations, all of whom spoke anonymously.

    By Monday, Axios had spoken to two sources with direct knowledge who said Gen. Dan Caine—the Joint Chiefs chairman and Trump’s most trusted military adviser—had privately been warning that any Iran campaign risked dragging the U.S. into a prolonged conflict. The same report revealed that Vice President JD Vance, as well as envoys Steve Witkoff and Jared Kushner, had each separately urged the president to give diplomacy more time.

    The Washington Post then reported that Caine had made his concerns explicit at a White House meeting last Tuesday—attended by Vance, Secretary of State Marco Rubio, CIA Director John Ratcliffe, Defense Secretary Pete Hegseth, and adviser Stephen Miller—warning that American munitions stockpiles had been significantly drained by the defense of Israel and support for Ukraine.

    The Post added that Arab nations had privately told Washington they would not permit their territory to be used for a strike, a logistical complication one unnamed former Pentagon official said was a critical obstacle.

    The pattern was flagged by journalist Branko Marcetic, who posted on X: “Someone in that administration is trying to head off what they realize will be a disaster.”

    The Wall Street Journal, whose account aligned closely with the Post’s, added a particularly sobering detail—that American interceptor supplies would last roughly a fortnight against a full Iranian missile assault, the Journal reported, with Patriot, THAAD, and SM-3 stockpiles already running critically low.

    The Ford is now on course for an 11-month continuous deployment, which would set a record. The carrier has been experiencing sewage problems, and sailors, the Journal reported, are overtaxed, with some considering leaving the Navy.

    The danger of overextending crews is not theoretical, the report said. It pointed to a Navy investigation into the loss of multiple fighter jets from the aircraft carrier USS Harry S. Truman during Houthi operations in the Red Sea in spring 2025, which concluded that the ship’s relentless operational tempo was to blame.

    Trump is issuing extreme demands that Iran is unlikely to comply with. So if this starts, hard to see the end point.

    Not knowing your end point is not a good way to start a war.

    ETA: The joint chiefs told Dubya it would take 500,000 troops to do an Iraq occupation. All Dubya/Cheney had available was 130,000 so they decided to go with that, they were that determined to have their war.

    I had not heard that. I knew the Brits had refused us Diego Garcia. I wonder if this includes Qatar, and/or Jordan, because that would be more than just a logistical complication. I really hope Donald isn’t going to try and take on Iran with carriers and US-based bombers alone.

    I was a bit surprised that Portugal let us use Lajes for refueling. US presence on Terçeira (Azores) has been drawn way, way down and the island doesn’t really rely much on the US for the local economy. I wonder about Rammstein. Are the Germans going along with this? Is Iraq OK with US overflights out of Jordan? How about the Saudis? Is overflight OK, bases not so much?

    I am all for regime change in Iran – in theory. Who doesn’t like watching a murderous regime brought down? But Bush/Cheney botched Iraq and as incompetent as they turned out to be, they’re strategic geniuses compared to the Trump gang.

    I can’t believe that neither Biden nor Trump launched an all-out effort to build our stockpiles of missiles. How are we proposing to fight China, if that war comes?
