Tucker Carlson has said Donald Trump should be removed from office 'immediately' if he is actively considering the first use of nuclear weapons, declaring that such a possibility must be an absolute 'red line' for any president.

Carlson made the remarks during a Friday discussion with Joe Kent, the former director of the National Counterterrorism Center who resigned earlier this year in protest of the Iran war. Carlson said he had strongly opposed Trump's first two impeachments but considered nuclear first use a fundamentally different issue.

'The second any president actively considers first use of nuclear weapons, that person should be removed from office immediately,' Carlson said, adding that anyone who tolerated such discussions was 'by definition unfit'.

Carlson's Nuclear Red Line

Carlson's comments followed a warning that the US was moving dangerously close to nuclear conflict. He argued that Trump's threats of Iran's 'total destruction' could amount to an implicit nuclear threat, although that is Carlson's interpretation rather than an established US policy.

Kent similarly warned that the administration's pursuit of regime change in Iran could eventually narrow its conventional options.

'I think we would be fools to think that this couldn't happen here in this current scenario,' Kent said, arguing that officials could ultimately face pressure to consider nuclear weapons.

The discussion came as the Pentagon reviews its nuclear strategy and considers whether the president should have more options for responding to regional conflicts.

Why the Pentagon Is Reviewing Nuclear Options

Undersecretary of Defense for Policy Elbridge Colby said the review was intended to provide the president and defence secretary with 'credible, rational nuclear options'. He said the goal was to strengthen deterrence and stability rather than make nuclear war more likely.

The review is reportedly examining shorter-range, lower-yield tactical nuclear weapons for potential regional conflicts. Their use could still carry the risk of wider escalation.

The review does not amount to a new US first-use policy. Washington already reserves the option to use nuclear weapons first under certain circumstances, while Colby has stressed that the review is intended to strengthen deterrence and provide additional options in a crisis.

That distinction is central to the dispute. Carlson has portrayed the nuclear review alongside Trump's rhetoric as an alarming trajectory, while Pentagon officials describe it as a deterrence measure.

Why Carlson's Break With Trump Matters

Carlson's position is particularly striking because he explicitly contrasted it with his opposition to Trump's previous impeachments.

'Why isn't there an attempt to remove him from office, like, immediately?' Carlson asked.

He argued that first use of nuclear weapons should cross a threshold that overrides ordinary political loyalty. His comments therefore amount to more than criticism of military policy: he is proposing a standard under which a president would become unfit to remain in office.

That puts Carlson at odds with Trump as the conservative movement remains divided over the Iran war and the administration's broader foreign policy.

Carlson has increasingly criticised the war and other aspects of Trump's second-term agenda while continuing to command a large conservative audience. His comments with Kent are therefore likely to attract attention beyond the nuclear-policy debate.

What the Nuclear Review Does — And Doesn't — Mean

The Pentagon's review should not be treated as evidence that the US is preparing to launch a nuclear strike against Iran.

Colby has said the purpose is deterrence, while reporting indicates officials are examining how nuclear forces could provide additional options in a regional conflict.

At the same time, Carlson's concern reflects a broader debate over whether expanding nuclear options could lower the threshold for their use. Arms-control advocates have warned that greater emphasis on tactical weapons could increase escalation risks, particularly in a conflict involving another nuclear-armed power.

The dispute is therefore not over whether nuclear weapons remain part of US strategy. It is over how much room a president should have to use them and whether creating more limited options could make nuclear use easier to contemplate.

Carlson's Warning to Trump

Carlson has not called for Trump's removal over the Iran war itself. His stated threshold is narrower: active consideration of first use of nuclear weapons.

There is no public evidence in the material for this article establishing that Trump has ordered or authorised preparations for a first nuclear strike against Iran.

What Carlson has done is draw an unusually explicit line between nuclear policy and presidential fitness. A man who once rejected attempts to remove Trump is now saying that contemplating first use of nuclear weapons would justify immediate removal.

Whether that warning gains wider support will depend on what emerges from the Pentagon's review and how the administration approaches the Iran conflict.

For now, Carlson's position is clear: whatever political disagreements Trump's supporters are prepared to tolerate, he says contemplating first use of nuclear weapons should cross the line.
