Trump tells Pentagon to immediately resume testing US nuclear weapons



By Trevor Hunnicutt, Ismail Shakil and Kanishka Singh

October 30, 20253:48 PM GMT+11Updated 5 mins ago


Summary

Decision follows China's nuclear stockpile expansion

Russia's recent nuclear tests include Poseidon super torpedo

China's arsenal expected to exceed 1,000 by 2030, CSIS says

BUSAN, South Korea, Oct 30 (Reuters) - U.S. President Donald Trump on Thursday ordered the U.S. military to immediately resume testing nuclear weapons, for the first time in 33 years, minutes before beginning a meeting with Chinese President Xi Jinping.

Trump made the surprise announcement on Truth Social while he was aboard his Marine One helicopter flying to meet Xi for a trade negotiating session in Busan, South Korea. He said he was instructing the Pentagon to test the U.S. nuclear arsenal on an "equal basis" with other nuclear powers.

"Because of other countries testing programs, I have instructed the Department of War to start testing our Nuclear Weapons on an equal basis. That process will begin immediately," Trump posted.
"Russia is second, and China is a distant third, but will be even within 5 years."
He did not elaborate and did not reply to a reporter's shouted question about his post after his initial remarks to Xi. It was not immediately clear whether Trump was referring to nuclear-explosive testing, which would be carried out by the National Nuclear Safety Administration, or flight testing of nuclear-capable missiles.



NEGATIVE REACTIONS TO TRUMP'S POST The reaction to Trump's announcement on testing was swift. Representative Dina Titus, a Democrat from Nevada, said on X: "I'll be introducing legislation to put a stop to this."
Daryl Kimball, director of the Arms Control Association, said it would take the United States at least 36 months to resume contained nuclear tests underground at the former test site in Nevada.
"Trump is misinformed and out of touch. The U.S. has no technical, military, or political reason to resume nuclear explosive testing for the first time since 1992," Kimball said on X.
It was not immediately clear whether Trump was referring to nuclear-explosive testing, which would be carried out by the National Nuclear Safety Administration, or flight testing of nuclear-capable missiles.
Kimball said Trump's announcement could "trigger a chain reaction of nuclear testing by U.S. adversaries, and blow apart the nuclear Nonproliferation Treaty."





https://www.ucs.org/sites/default/files/attach/2015/05/Hair-Trigger-Alert-Policy...


The United States and Russia each maintain roughly 900
nuclear weapons on prompt-launch status—commonly called
high alert or hair-trigger alert—so they can be launched in
minutes.


Prompt-launch status, however, increases the risk
that weapons could be launched by accident, without
authorization, or by mistake in response to a false warning of
an incoming attack.
Current tensions with Russia make it even more
important to ensure that a crisis—with its attendant increase
in opportunities for misunderstandings and time pressure on
decision makers—does not lead to a mistake that triggers an
unintended nuclear exchange.
As a first step to increasing security, the United States and
Russia should remove their silo-based missiles from hairtrigger alert. But even without Russian reciprocation, the
United States would enhance its own security—and that of the
world—if it took this action. U.S. land-based missiles can be
removed from hair-trigger alert by utilizing an existing safety
switch in the silos that is routinely used to prevent launches
during maintenance.

The U.S. is still on a "hair trigger" for its land-based and submarine-based nuclear weapons,
meaning they can be launched within minutes of an order.


This posture is a legacy of the Mutual Assured Destruction (MAD) doctrine and remains in place because they can be launched rapidly upon warning of an attack, though current U.S. policy does not require an irrevocable launch. Some argue that keeping these weapons on high alert increases the risk of accidental war during a crisis, while others maintain they are necessary for deterrence and strategic stability, with safety measures in place.
Status of "hair-trigger" alert

Land-based and submarine-based missiles: Approximately 450 silo-based missiles and hundreds of submarine-based weapons are kept on high alert, allowing for a rapid launch response.
Bombers: The U.S. no longer keeps bombers armed and on constant alert.
Arguments for and against the policy


Arguments for:
Deterrence: The rapid launch capability is intended to deter an enemy from launching a first strike, ensuring a retaliatory strike is possible.
Strategic stability: Proponents of the policy argue that this posture maintains strategic stability.


Arguments against:
Risk of accidental launch: Critics argue that the "hair-trigger" posture increases the risk of accidental, mistaken, or unauthorized launch, especially during a crisis or if a warning is based on a false alarm or a computer error.
Escalation: Some believe that taking land-based missiles off high alert could reduce this risk and encourage Russia to do the same, further benefiting security.

It's 80 years since Hiroshima and Nagasaki
and still every person in the world has the threat of being killed by nuclear weapons.
The fact that many are on a hair trigger is disgraceful.

All it would need is for human beings to declare that it's not acceptable
and verifiable rules to be put into place to stop hair trigger systems,
and the gradual dismantling and removal of all nuclear weapons.

You'd think 80 years would be long enough to do it?
It depresses me to see how pathetic our world leaders have always been.

If it were really a hair trigger, it must have been a mammoth hair.

Robert Floyd, head of the Vienna-based Comprehensive Nuclear-Test-Ban Treaty Organization, expressed alarm.
"Any explosive nuclear weapon test by any state would be harmful and destabilising for global non-proliferation efforts and for international peace and security," he said.


U.N. Secretary-General Antonio Guterres has repeatedly said current nuclear risks are already alarmingly high and urged countries to avoid all actions that could lead to miscalculation or escalation with "catastrophic" consequences, said deputy U.N. spokesperson Farhan Haq.
"As he has said, we must never forget the disastrous legacy of over 2,000 nuclear weapons tests carried out over the last 80 years, and that nuclear testing can never be permitted under any circumstances," said Haq.

So a disastrous legacy that has not occurred apart from a failed USSR design and workmanship.

The world is being held hostage? It seems more like it is keeping the madmen in check.

This is the Environment MRB.
Should I go into great detail about all the radioactive pollution in the world?
It's a simple Google search that anyone could do and doesn't need me to prove it.
Radioactive waste has been dumped in our oceans,
nuclear sites are still so contaminated that no one can live there.
The Russians still have old nuke subs rusting away in ports.

Not without dropping Linear No Threshold theory. Wink


Google AI:

The linear no-threshold (LNT) model is a model used in radiation protection that assumes a direct, proportional relationship between radiation dose and the risk of stochastic health effects like cancer, meaning there is no "safe" threshold for radiation exposure. This model is the basis for current radiation protection regulations and the "as low as reasonably achievable" (ALARA) principle, and is intended as a precautionary measure because the risks at very low doses are difficult to measure. However, the LNT model is controversial, with some experts suggesting that low doses may not be harmful or could even be beneficial (a concept known as hormesis), and there is an ongoing scientific debate about its accuracy at low doses. 


Key assumptions of the LNT model
Linear dose response: The risk of cancer is directly proportional to the dose. A higher dose equals a higher risk, in a straight-line relationship.


No threshold: There is no dose below which the risk of harm is zero. Every increment of radiation, no matter how small, increases the risk.


Precautionary principle: The model is a conservative approach to ensure safety, especially when the effects of low-dose exposure are not well understood.


Applications and implications
Radiation protection: The LNT model forms the foundation for international radiation protection systems and regulations.
Risk assessment: It is used to estimate the risk of cancer and other health effects from radiation exposure, for example, in determining cleanup levels for contaminated environments.


ALARA principle: The "as low as reasonably achievable" (ALARA) principle stems from the LNT model, promoting the reduction of radiation exposure to the lowest possible levels.


Controversy and debate
Scientific debate: The LNT model is subject to scientific debate, and its validity at low doses is questioned by some experts.
Hormesis: Some scientific evidence suggests that low-level radiation exposure might have a beneficial effect (hormesis), which contradicts the LNT model.


Statistical limitations: At very low doses, the risk is difficult to detect and measure due to the small number of affected individuals compared to the total population and the limitations of statistical data.
Human repair mechanisms: The model is criticized for not fully accounting for the body's natural DNA repair mechanisms and other protective biological processes that are effective at low doses.

The human body can repair itself from sunburn (radiation). Of course constant sunburn is not desired.

As I have said previously, it is flawed.

In this video, we discuss the amazing true scale of America's Nuclear Weapons, particularly the LGM-30 Minuteman III.

The LGM-30 Minuteman III is a three-stage solid-fuel intercontinental ballistic missile with a complex guidance system and stands as American’s land-based nuclear deterrent. As of 2025, the United States has 400 Minuteman intercontinental ballistic missiles deployed, fully armed, ready to be launched from their silos at the President's command.

In this video, we take a detailed look at the missile's W-87 300 kiloton Nuclear Warhead, the Post Boost Vehicle that delivers the warhead, the ICBM's three solid fuel stages, the missile's flight sequence, and ultimately simulate the detonation of its warhead over the capital of China, the city of Beijing with a population of 22 million Chinese civilians.

Should Australia build its own nuclear weapons?

With global tensions rising and the Indo-Pacific becoming more unpredictable, some argue that Australia should go nuclear to protect itself. But would that actually make us safer or just make the region more dangerous?

We look at why countries want nukes, what it would take for Australia to build one, and the legal, strategic, and practical barriers that stand in the way. From the Nuclear Non-Proliferation Treaty to AUKUS submarines, long-range strike capabilities, and autonomous defence tech—this is the story of how Australia already has powerful deterrence options without crossing the nuclear line.
