A senior political advisor to Iran's Supreme Leader warned that any American military action against Iran, at any level, would be treated as the opening act of a full-scale war, with retaliation aimed not only at U.S. forces but at Israel and anyone backing Washington.
Ali Shamkhani, former secretary of Iran's Supreme National Security Council and a current advisor to Supreme Leader Ali Khamenei, posted the threat on X in both Persian and Hebrew. The language left no room for ambiguity.
As Newsweek reported, Shamkhani wrote:
"A limited [U.S.] strike is an illusion. Any military action by America, of any kind and at any level, will be considered the start of a war, and the response will be immediate, comprehensive, and unprecedented, directed at the aggressor, at the heart of Tel Aviv, and at all who support the aggressor."
The statement came as President Trump revived the threat of a military strike against Iran and ordered what he called an "armada" to the Middle East, led by the aircraft carrier USS Abraham Lincoln. The Lincoln is expected to conduct military drills in the region soon.
Tehran's mixed signals: war talk and negotiation offers
What makes the Iranian posture worth watching closely is the contradiction running through it. Shamkhani's threat was not the only message Tehran sent. On the same general timeline, Speaker of Iran's Parliament Mohammad Bagher Ghalibaf struck a markedly different tone.
Ghalibaf said Thursday, per Iranian state media, that Trump may be able to start a war but has no control over how it will end. Then he added something that didn't quite match the fire-and-brimstone from Shamkhani:
"We are ready for sincere and genuine negotiations with America."
That's the Iranian regime in a single frame, threatening total war out of one side while extending an olive branch out of the other. The pattern is old. The question is whether anyone in Washington still falls for it.
Iranian Foreign Minister Abbas Araghchi added his own layer of rhetoric. He said Iran's armed forces stand ready for immediate action:
"Our brave Armed Forces are prepared, with their fingers on the trigger, to immediately and powerfully respond to ANY aggression against our beloved land, air, and sea."
Three senior Iranian officials, three statements, and no single coherent message. That's not strength. That's a regime hedging its bets.
The American posture: 40,000 troops in range
Secretary of State Marco Rubio laid out the stakes plainly during a Senate hearing. CNN reported that Rubio told senators up to 40,000 American soldiers are currently stationed in the Middle East within range of Iranian missiles or drones. That number alone explains why the administration is not treating Iran's nuclear ambitions as a problem to be managed with polite diplomacy.
Rubio also stated that Trump has the option of launching a defensive preemptive strike. He acknowledged uncertainty about what comes after any confrontation with the regime, noting that no one knows who would lead Iran should Khamenei's government fall.
That is a candid admission, and a responsible one. It separates the administration's posture from the kind of reckless, plan-free interventionism that plagued earlier Middle East conflicts. Knowing the risk does not mean avoiding the threat. It means confronting it with open eyes.
Reuters reported that Trump is weighing options aimed at creating conditions for regime change, including targeted strikes on security forces and leaders. Newsweek contacted the White House for comment on the Iranian threats.
The pattern Tehran hopes Americans forget
Iran's leadership has spent decades perfecting a cycle: provoke, threaten, negotiate under pressure, extract concessions, then resume provocations. The 2015 nuclear deal, the Joint Comprehensive Plan of Action, was the clearest example. Tehran got sanctions relief and billions in unfrozen assets. In return, the regime slow-walked inspections, expanded its ballistic missile program, and continued funding proxy forces across the region.
Shamkhani's threat to strike "the heart of Tel Aviv" is not a new kind of rhetoric from Tehran. It is the same eliminationist language Iranian leaders have used for years. What is different now is the American response. Trump's decision to send a carrier strike group and openly discuss preemptive options signals that Washington is done pretending the threat will resolve itself through goodwill.
The fact that Shamkhani posted his warning in Hebrew, directed squarely at an Israeli audience, tells you everything about who Iran considers its primary target. The regime wants Americans to believe this is a bilateral dispute. It is not. It is a regional threat with nuclear implications.
Negotiation or escalation?
Ghalibaf's offer of "sincere and genuine negotiations" deserves exactly as much trust as Iran's track record warrants. This is a government that crushed antigovernment protests at home, has been under sustained pressure from Washington over that crackdown, and continues to expand its nuclear program while claiming peaceful intent.
Trump's latest threat reportedly followed a statement that Iran was ready for a deal with Washington. The sequence matters. Tehran floats willingness to talk, then the president raises the military pressure, and then Iranian officials pivot to threats of total war. The regime wants the appearance of reasonableness without any of the substance.
Forty thousand American service members are deployed within striking distance of Iranian weapons. The USS Abraham Lincoln is heading to the region. And Iran's senior national security advisor is promising an "immediate, comprehensive, and unprecedented" response to any action.
Those are the facts on the table. They do not describe a situation where patience and process will do the work.
What the threats reveal
Shamkhani's warning, that even a limited strike would trigger all-out war, is designed to deter. Every regime facing superior military force uses the same playbook: make the cost of action sound so catastrophic that the stronger party backs down. Iran has no conventional military that can match the United States. Its leverage is chaos, missiles aimed at allies, proxy attacks on bases, and the threat of a wider regional conflict.
But deterrence only works if the other side believes the threat is credible and finds the status quo acceptable. The Trump administration has made clear it finds neither condition met. Rubio's acknowledgment that a preemptive strike is on the table is not saber-rattling. It is an honest assessment of where things stand when a hostile regime inches toward a nuclear weapon while 40,000 Americans sit in its crosshairs.
Iran's leaders are talking out of both sides of their mouths because they are not sure which message will work. That uncertainty is itself a product of American strength, not weakness.
When a regime threatens total war and offers negotiations in the same breath, it is not showing resolve. It is showing fear dressed up in defiance, and Washington should act accordingly.
