American political commentator Tucker Carlson has issued an extraordinary warning that President Donald Trump could be just days away from authorising a nuclear strike against Iran, alleging that Israeli Prime Minister Benjamin Netanyahu is exerting intense pressure on Washington to attack a deeply buried Iranian nuclear facility.
Carlson warned that such an attack could trigger consequences far beyond the Middle East, potentially contaminating the Gulf’s water supplies, devastating an already weakened global economy and establishing a precedent for other nuclear-armed countries to use their own weapons.
In a lengthy post on X, Carlson claimed that the Trump administration is approaching a decision that could fundamentally alter the international order, with the possibility of a nuclear strike emerging as diplomatic efforts continue in Doha to end the war.
His warning centres on a suspected underground Iranian nuclear facility known as “Axe Mountain”, where Israeli intelligence claims Tehran has resumed uranium enrichment.
According to Carlson, the facility’s location beneath hundreds of feet of solid granite could leave the United States with no conventional military option capable of destroying it.
The claims, which include allegations about American military planning and international nuclear threats, were presented by Carlson as warnings about a possible escalation, rather than confirmation that Washington has authorised a nuclear attack.
The Underground Iranian Facility at the Centre of the Nuclear Warning
Carlson argued that the immediate danger stems from Israeli pressure to destroy a suspected uranium-enrichment site buried deep inside a mountain in central Iran.
According to his account, Israeli intelligence believes the Iranian government has restarted uranium enrichment at the facility, prompting renewed demands for American military action.
However, Carlson claimed that the physical characteristics of the site present a major obstacle to conventional weapons.
He argued that no conventional weapon in the American arsenal could penetrate approximately 300 feet of solid granite to destroy the underground tunnels where enrichment is allegedly taking place.
On that basis, Carlson asserted that a nuclear strike would be the only military option capable of destroying the facility.
The claim places the suspected Iranian site at the centre of a potentially unprecedented decision by Washington: whether to employ a nuclear weapon against a country in pursuit of an underground military target.
Carlson alleged that Netanyahu has been pressing Trump to authorise such an attack.
Citing an informed observer, he wrote that the Israeli prime minister has been maintaining direct and persistent contact with the American president.
“Bibi calls Trump about this every day,” the observer reportedly said, using Netanyahu’s familiar nickname.
The allegation suggests that the pressure for military escalation is not limited to discussions between defence establishments but extends directly to the highest levels of American and Israeli leadership.
Carlson Accuses Senior US Officials of Supporting Renewed War
Carlson’s allegations extended beyond Netanyahu to senior figures within the Trump administration whom he accused of opposing a negotiated settlement with Iran.
According to Carlson, the Israeli prime minister has applied maximum pressure on his closest allies in Washington, including US Defence Secretary Pete Hegseth and General Brad Cooper, commander of US Central Command (CENTCOM).
Carlson claimed that both officials oppose a diplomatic agreement to end the war, which he accused them of having seriously mismanaged.
He further alleged that both are advocating the resumption of major military operations against Iran.
His criticism also extended to Secretary of State Marco Rubio and CIA Director John Ratcliffe, whom he portrayed as supporting Netanyahu’s approach.
Carlson argued that the push for continued confrontation is not confined to Republican officials.
He claimed that leading figures within the Democratic Party are also aligned with the Israeli prime minister’s position.
Among his more striking allegations was that former President Barack Obama had expressed opposition to a peace agreement currently being drafted through negotiations in Doha.
According to Carlson, Obama made his position known during a recent meeting concerning the proposed settlement.
Taken together, Carlson’s allegations describe a political and military establishment in Washington in which influential figures from both major parties favour continued confrontation with Iran over a negotiated conclusion to the war.
Eight Months of War Have Already Shaken the Global Economy
Carlson argued that the consequences of another military escalation must be considered against the economic damage already caused by eight months of confrontation.
He warned that Gulf economies, global energy markets and international fertiliser supplies have suffered severe disruption, with little prospect of a rapid recovery.
His concerns focused particularly on the vulnerability of maritime oil transportation.
According to figures cited by Carlson, approximately 850 supertankers operate worldwide, transporting oil from producing countries to international markets.
He claimed that 11 of those vessels were severely damaged in the Strait of Hormuz during October alone.
At that rate, Carlson warned, the disruption to global oil transportation could help push the world towards an economic depression.
The significance of these claims lies in the Strait of Hormuz’s role in international energy transportation and the vulnerability of shipping routes during periods of military confrontation.
Carlson argued that the existing damage to global markets is already severe, even without the additional consequences of nuclear warfare.
A nuclear strike, he warned, would dramatically accelerate the destruction.
A Nuclear Explosion Could Contaminate Water Supplies for 100 Million People
One of Carlson’s most alarming warnings concerned the environmental and humanitarian consequences of detonating a nuclear weapon against a deeply buried Iranian facility.
According to his assessment, a nuclear explosion at Axe Mountain would generate radioactive fallout capable of contaminating the Arabian Gulf.
He warned that the resulting pollution could poison water supplies relied upon by approximately 100 million people.
The claim raises the prospect of a humanitarian catastrophe extending well beyond Iranian territory, potentially affecting populations across the Gulf region.
Carlson presented this scenario as one of the immediate regional consequences of a nuclear attack.
He also cautioned that the environmental destruction would represent only part of the danger.
In his assessment, the consequences for the wider international community could be equally severe, particularly if the use of a nuclear weapon by the United States encouraged other nuclear powers to abandon longstanding restraints.
His warning therefore extended beyond the potential casualties and contamination resulting from a single American strike.
He argued that the greater danger could be the precedent such an attack would establish.
Could an American Nuclear Strike Trigger a Global Nuclear War?
Carlson warned that an American nuclear attack against Iran could fundamentally change how other nuclear-armed governments assess the use of their own arsenals.
He claimed that Russian officials had already communicated to at least two other governments that an American nuclear strike on Iran would give Moscow greater freedom to employ nuclear weapons against Ukraine.
According to Carlson, the danger would not be limited to Russia.
He suggested that Pakistan and India could become more willing to consider nuclear weapons against each other.
North Korea, he warned, could likewise be encouraged to contemplate nuclear action against Seoul.
Carlson’s argument was that the first use of a nuclear weapon in the current confrontation could dismantle restraints that have historically discouraged nuclear escalation.
Rather than remaining confined to the Middle East, he feared that the precedent would spread across several of the world’s most dangerous military flashpoints.
He presented the potential consequences in stark terms.
“After the first nuclear strike, World War III becomes inevitable,” Carlson warned, adding that such a war would be “short and final”.
The prediction represents Carlson’s assessment of the risks, rather than an established or inevitable outcome of an American attack.
Nevertheless, it formed the central argument of his warning: that a military decision ostensibly intended to destroy an Iranian nuclear facility could create conditions for nuclear confrontation far beyond the region.
Carlson Claims Washington Has Quietly Changed Its Nuclear Doctrine
Beyond the immediate pressure surrounding Iran, Carlson raised another allegation about changes within American military policy.
He claimed that since February, the Trump administration has quietly rewritten US nuclear doctrine to make the first use of so-called tactical nuclear weapons easier and therefore more likely.
Carlson presented the alleged changes as particularly dangerous because they could lower the threshold for employing nuclear weapons during an ongoing military confrontation.
He also criticised the apparent absence of opposition from Washington’s political establishment.
According to Carlson, influential figures in both major American parties have failed to demonstrate sufficient concern about the possibility of nuclear escalation.
He suggested that the combination of military pressure, political consensus and a more permissive approach to nuclear weapons had brought the United States dangerously close to a catastrophic decision.
“Now we are on the brink,” he warned.
‘The Only People Who Haven’t Been Consulted Are the People of the World’
Carlson concluded by shifting his attention away from political leaders and military commanders towards the populations who would bear the consequences of a nuclear confrontation.
He argued that the people most vulnerable to the effects of such a war have been excluded from the decisions that could determine their survival.
“The only group that has not yet been consulted is the people of the world,” he wrote.
Carlson warned that hundreds of millions of people, including children, could face death if Netanyahu succeeded in persuading Trump to authorise a nuclear strike against Iran in the coming days.
His final appeal called on ordinary people to make their opposition known before such a decision could be taken.
“Now is the time for them to raise their voices,” he concluded.
