As global leaders respond to US President Donald Trump’s major nuclear weapons announcement, here’s what a renewed arms race could mean for the future of humanity.
ANALYSIS
Nuclear tests — or testing nukes?
The distinction is critical, carrying serious global consequences.
The future could depend on US President Donald Trump’s understanding of that difference — whether he’s engaging in madman” politics or acting on the guidance of his intelligence advisors.
Global Fallout — Trump’s Nuclear Weapons Announcement and the Future of Humanity
Due to other nations’ testing programs, I’ve directed the Department of War to begin testing our nuclear weapons on an equal footing,” the President recently declared.
The process, he said, would begin immediately.
Since then, strategic experts around the world have been scrambling to interpret his statement.
British strategist Lawrence Freedman observed that the announcement seemed to stem from a misunderstanding of what other countries are actually doing and lacked clear strategic or practical reasoning.
As with many of Trump’s bold declarations, this one appeared to come without thorough staff preparation or fact-checking.
Nuclear Tests or Testing Nukes – Why the Difference Matters
Was he referring to testing nuclear warheads? That’s what his words appeared to suggest.
Or was it about testing the delivery systems for those warheads? That’s exactly what Russia has just done.
Could it have been a response to China’s rapidly growing nuclear arsenal? After all, the statement came just before Trump’s meeting with Xi.
Trump’s Call for Equal Testing – Confusion and Concern Among Analysts
There are suspicions that Russia and China might be secretly conducting nuclear explosive tests in ways that evade international detection,” says Matthew Kroenig, vice president of the Atlantic Council.
However, no concrete evidence has been provided to support these allegations.
Despite this, President Trump seems convinced he knows the truth.
You’ll find out very soon,” he told reporters aboard Air Force One on Saturday (Australian time). “We’re going to do some testing — yes. Other countries are doing it, and if they are, we will too.
Was It About Warheads, Delivery Systems, or China’s Arsenal?
Russia holds a larger nuclear stockpile than the United States, primarily due to its vast collection of short- and medium-range weapons.
The modernization of America’s nuclear arsenal actually began during the Obama administration, focusing on replacement rather than expansion.
Meanwhile, China is rapidly advancing its nuclear capabilities, but it’s unlikely to reach parity with the US or Russia by 2030.
No other nation is currently conducting nuclear tests — so what exactly does “on an equal basis” mean?
Moreover, the US couldn’t begin testing right away, and if it did, the responsibility would lie with the Department of Energy, not the Pentagon.
Aside from those points, he’s largely correct.
Chain reactions
This has all the signs of another impulsive Trump initiative,” says Sir Lawrence Freedman. That’s why we may see a burst of activity as officials scramble to interpret his intentions — until it becomes too complicated and quietly fades away. And for several reasons, that outcome seems most likely.
President Trump certainly has nuclear issues on his mind.
Meanwhile, President Putin’s propagandists have once again suggested a “demonstration” meant to intimidate NATO from backing Ukraine — potentially involving the detonation of a small nuclear warhead in a remote, neutral Arctic area.
While it’s unwise to completely ignore such extreme rhetoric, in reality, it’s nothing more than bluff, brinkmanship, and sheer nonsense,” says defence and security expert Stuart Crawford.
Chain Reactions – Rising Tensions and Political Theatre
There is absolutely no chance that his threat will actually be carried out.
Earlier this year, tensions between Pakistan and India escalated from mutual accusations of supporting terrorism to open nuclear posturing within just 24 hours. At the same time, President Trump, alarmed by Iran’s perceived nuclear threat to Israel, authorized strikes on its underground nuclear facilities.
Amid these global tensions, the last remaining Cold War-era nuclear arms treaty is set to expire in February.
Talks to renew the Strategic Arms Reduction Treaty (START) have yet to begin. So far, President Trump has remarked only that such discussions “sound like a good idea,” while President Putin has also expressed interest. However, Trump insists that no agreement will move forward unless China joins the deal.
Whether any framework will be negotiated to extend these restrictions beyond February remains uncertain. None of the nuclear-armed powers are currently pursuing new treaties,” explains Dr. Tilman Ruff from the University of Melbourne.
As a result, the Doomsday Clock — one of the most respected measures of global existential risk — has advanced further this year than ever before. It truly is an extraordinarily dangerous moment in human history.
Testing times
The mention of ‘nuclear testing’ instantly brings to mind images of towering mushroom clouds and distant explosions,” notes Heather Williams, a nuclear analyst at the Centre for Strategic and International Studies (CSIS).
However, modern nuclear weapons research has advanced far beyond the dramatic tests of the early Cold War era. The United States now relies on cutting-edge technology — including high-energy lasers and advanced supercomputers at national laboratories — to ensure the safety and reliability of its arsenal.
In simple terms, the US no longer needs to detonate bombs to test its nuclear capabilities. It has already carried out 1,054 closely monitored tests, compared to Russia’s 715 and China’s 47.
In a renewed nuclear testing race, the only real beneficiary would be Beijing.
Impulsive or Strategic? Inside Trump’s Nuclear Gamble
This imbalance in testing data has long frustrated Chinese officials, who believe they were put at a disadvantage by arms control agreements like the Partial Test Ban Treaty,” explains Williams. “If one nation resumes nuclear testing, others are likely to follow.
China’s nuclear buildup now mirrors the rapid expansion of its naval power. Massive new intercontinental ballistic missile (ICBM) fields are under construction in the remote deserts of Xinjiang.
Beijing is estimated to possess around 600 nuclear warheads, a number expected to exceed 1,000 by 2030.
The White House has expressed concerns that China may have been conducting secret nuclear detonations. A 2020 U.S. Department of State report stated it could not rule out the possibility of covert testing at China’s Lop Nor site, which has since undergone major expansion.
The department’s 2022 report further accused Russia of violating the Comprehensive Test Ban Treaty’s (CTBT) “zero-yield” clause, noting similar developments at Moscow’s Novaya Zemlya testing facility.
Even extremely small nuclear tests may not generate a detectable seismic signal,” Williams adds, “but they can still trigger a nuclear chain reaction — providing valuable data on weapon design and fissile material behavior, in clear breach of the CTBT.
