A number of US military top generals have taken the rare step of formally registering warnings to Pentagon chief Pete Hegseth over potential plans for a new phase of strikes against a non-compliant Iran. 

The warnings reportedly emerged through the Secretary of Defense Orders Book, which enumerates the availability of US military resources and force posture around the world - with direct input from American regional commanders.

The book is typically published twice a month, but this time it was reportedly filled with pushback by those overseeing operations in Latin America, Europe and Asia - who have seen training missions canceled, and ships and aircraft diverted to the Middle East for counter-Iran operations.

The Washington Post reported over the weekend that a chief complaint by the top officers was that the Iran conflict "has degraded their ability to fulfill homeland-defense obligations."

Amid fresh troop movements based on new orders reportedly issued in mid-August, commanders made clear they do not agree with the new force trajectory, but are ready to carry out the Commander-in-Chief's orders regardless.

Still, the leaking of this information, and such a rare public airing of grievances, has Hegseth and the Trump administration furious. The Washington Post reports:

The Aug. 14 orders book directs some troops deployed in the Middle East to remain there through September and some others into 2027, said those familiar with the document. The prospect of extending those forces further compelled military leaders to voice their concern, these people said.

Leaders of the U.S. European Command, the U.S. Pacific Command and the U.S. Southern Command, along with the Navy’s top admiral, responded with what is characterized in the SDOB as a “non-concur,” those familiar with the assessment said — meaning they disagree with the secretary’s order to extend their forces but will execute it nevertheless.

Another key line from generals cited in the WaPo reporting is that the Iran war - which the Trump White House early on had promised would be 'swift' - has been "too much for too long".

Some pundits are warning that this alleged rare leak is an alarming sign Trump could be preparing to do something 'big'...

That section from the WaPo report reads as follows:

Army and Air Force leadership concurred with Hegseth’s desire to extend their deployed forces, but each emphasized that doing so would come with significant risk, these people said.

Overall, the tenor from the military leadership is that the ongoing Iran operation, having reached the six-month mark, has been “too much for too long,” said one person familiar with the assessment.

The military’s warning to Hegseth, which has not been previously reported, offers new insight into the administration’s dilemma as Trump seeks to end the conflict on terms favorable to the United States while Iran, cognizant of the war’s unpopularity with most Americans and its mounting toll on the U.S. arsenal, refuses to capitulate.

As expected, the Pentagon has responded by calling it fake news and saying that leakers of classified information will be sought and dealt with.

"This fake news, poorly sourced reporting is full of inaccuracies," Chief Pentagon Spokesman Sean Parnell said in a statement. More from Parnell on X:

He added: "Decisions regarding the scope and duration of specific force commitments to any Combatant Command are made based on the current threat assessment, strategic priorities established by the President, and the advice of the Chairman of the Joint Chiefs of Staff and Combatant Commanders. However, the Department of War does not discuss internal operational processes, including the Secretary of War Orders Book (SWOB), or specific concurrences, non-concurrences, or risk assessments provided by the Services or Combatant Commands during force allocation deliberations."

But the reality is that this conflict is a full six months in, and the generals are perhaps keenly aware it is now in quagmire stage, with no plans for an exit or final strategic 'mission accomplished' vision in sight. Meanwhile, every escalation in the Persian Gulf tends to beget more escalation. What's the endgame here?
