As Chairman of the Joint Chiefs of Staff, Dan Caine faces one of the most delicate assignments in modern civil-military history: preparing detailed military plans for a potential war with Iran while maintaining influence with President Donald Trump, a commander-in-chief known for unpredictability and public bravado.
Behind closed doors at the Pentagon, Caine has been drafting a broad range of military options targeting Iran’s nuclear and missile infrastructure, and even contingency scenarios involving regime change. At the same time, he has privately raised concerns about the scale, risks, and unintended consequences of such an operation, according to officials familiar with internal discussions.
The result is a careful balancing act: offering candid professional advice while avoiding the kind of public friction that defined Trump’s relationship with former Joint Chiefs Chairman Mark Milley during Trump’s first term.
Quiet Planning in a Leak-Wary Administration
Unlike traditional deliberations held in the Pentagon’s secure conference room known as “the Tank,” Caine has reportedly summoned senior Army, Navy, and Air Force officials to his private office to discuss Iran contingencies. The goal: minimize leaks in an administration intensely focused on secrecy.
Military options under review reportedly include:
- Precision strikes on ballistic missile facilities
- Attacks on nuclear enrichment infrastructure
- Cyber operations
- Broader campaigns aimed at destabilizing Iran’s leadership
These plans are being developed alongside ongoing diplomatic efforts, a dual-track strategy combining negotiations with visible military buildup.
Over the past month, the US has assembled one of its largest military deployments in the Middle East since the Iraq invasion, including carrier strike groups and advanced aircraft positioned as deterrence.
Private Caution vs. Public Confidence
While Trump has publicly suggested that a military confrontation with Iran would be swift and decisive, Caine has reportedly been more measured in private briefings. Sources say he has warned of:
- Potential US casualties
- Regional escalation
- Iranian asymmetric retaliation
- Long-term instability following regime change
During a recent Situation Room meeting that ran three times longer than scheduled, Caine was reportedly unable to predict with confidence the outcome of a regime change operation — a contrast to earlier operations such as the January 2026 capture of Venezuelan leader Nicolás Maduro.
Still, Trump has publicly praised Caine, describing him as a general who “only knows how to WIN.”
Learning from the Milley Era
Caine’s approach appears shaped by the turbulent tenure of his predecessor, Gen. Mark Milley, who frequently clashed with Trump over domestic troop deployments and presidential rhetoric.
Where Milley sometimes positioned himself as a guardrail against politicization, Caine has chosen a lower-profile, restrained posture. He rarely injects personal opinions and focuses on presenting a “full spectrum” of military options, according to Pentagon officials.
Critics argue that Caine may be overly cautious in confronting presidential assumptions. Supporters counter that his job is to advise, not dictate policy.
Managing Pentagon Politics
Caine’s balancing act extends beyond Trump.
Defense Secretary Pete Hegseth has clashed with senior officers over personnel decisions and strategic priorities. Caine has reportedly tried, sometimes unsuccessfully, to shield certain senior officials from abrupt dismissals.
At the same time, he has worked to repair strained relations between the Joint Staff and the Secretary’s office, particularly after suspicions of internal leaks.
Observers describe Caine as soft-spoken, politically cautious, and deeply aware of the constitutional principle of civilian control of the military, even when decisions cause internal unease.
The Face of Major Operations
Despite preferring to remain behind the scenes, Caine has occasionally been thrust into the spotlight.
He delivered technical briefings defending US strikes on Iranian nuclear facilities and provided dramatic accounts of the operation that captured Venezuela’s former president.
Still, unlike past chairmen, Caine avoids media exposure. Joint Staff interactions with reporters are now tightly controlled, reflecting broader administration messaging discipline.
Preparing for War, Hoping for Peace
As tensions with Iran escalate, Caine must prepare for worst-case scenarios while ensuring the military remains apolitical and professionally grounded.
Privately, he has emphasized restoring trust in the institution of the military — even as political polarization intensifies.
The fundamental challenge remains: how to provide unvarnished military advice without becoming part of a political confrontation.
