The challenge with all such posts is that they never tell the whole story. Yes, Russia and China are refusing to enter arms control negotiations with the United States and Russia is believed to be conducting hydronuclear tests that produce a nuclear yield, but the President’s post does not mean what you may think.

Contrary to the wailing and gnashing of teeth of arms control advocates after Trump’s post, he is not calling for a return to detonating nuclear warheads under the Nevada desert. He is calling for something much different, which is why his post included, “…on an equal basis.” This point is important and was seemingly lost on many.

What many Americans may not know is that the United States last tested a nuclear weapon in 1992 and has, since at least 1996, interpreted the Comprehensive Test Ban Treaty (CTBT) to mean that nuclear testing cannot produce a nuclear yield. Thus, the United States, has voluntarily followed the CTBT and produced “zero yield” in the many tests it has conducted over the past three decades. American scientists were able to verify the continued safety, security, and effectiveness of the nation’s nuclear arsenal without producing an explosive yield.

President Trump is simply enabling American scientists to conduct hydronuclear tests that can provide higher fidelity results as the nation modernizes its existing nuclear warheads and begins building the first new nuclear warhead in more than a generation. This is a very important distinction.

The President, who often speaks in generalities, can be faulted for not offering a level of detail that explained his post more clearly, but articles claiming he does not understand nuclear testing may be less accurate than the President’s critics believe. The relationship between the Department of War and the Department of Energy, when it comes to nuclear weapons, is symbiotic. The Department of Energy designs and builds the weapons at its federally funded and privately operated labs, under the management of the National Nuclear Security Agency, but the Department of War drives the demand for capabilities. Thus, criticizing the President for saying the Department of War will do the testing is a bit of a hollow victory.

With Russia unwilling to extend New START and China’s continuing unwillingness to join multilateral arms control negotiations, President Trump’s statement was an attempt at demonstrating American resolve in the face of America’s declining nuclear position. The reality is that Russia understands its strength is in its nuclear forces, not its conventional capabilities.

If President Trump deserves criticism for anything, it is incorrectly suggesting that the American nuclear arsenal is superior to that of Russia; it is not. Russia’s arsenal is both newer and larger than that of the United States.

Russia may also breakout of New START limits upon the treaty’s expiration, which is a worrying prospect for the United States. Russia’s abrogation the Comprehensive Test Ban Treaty (CTBT) in 2023, in retaliation for Western support of Ukraine, is also concerning. It is, however, unsurprising. Before, Russia at least tried to ensure any violations of the “zero yield” understanding was hidden from the global public. That may cease if the Ukraine war continues. Although, President Trump’s announcement may have contained Russian ambitions.

Russia may have announced “reciprocal measures” if the United States begins testing, but Vladimir Putin knows the US is looking to conduct tests at the same level as Russia’s existing tests. China called on the US to uphold the moratorium on nuclear testing, but China may have also violated the “zero yield” threshold in its effort to build advanced nuclear weapons. Unfortunately, neither the Chinese nor Russian programs is particularly visible to Western monitoring efforts.

The prospects for Russo-American cooperation are low, but this should come as no surprise considering nuclear weapons are Russia’s trump card, no pun intended, when it comes to limiting Western support to Ukraine. Putin cannot afford to lose in Ukraine. His head, quite literally, is on the line.

Chinese nuclear forces are still inferior to American nuclear forces, but not for long. Thus, joining multilateral negotiations are not in China’s core interests as the Chinese Communist Party builds a nuclear arsenal fit for deterring American intervention with Chinese plans to seize Taiwan and perhaps other disputed territories. Of course China responded to President Trump’s post by calling it “unreasonable and unrealistic.” Hypocrisy on nuclear issues will not, however, stop Chinese communists from expanding their arsenal.

President Trump’s post is understandable given the world in which he finds himself. The President must try to deter continued Chinese and Russian aggression. If resuming nuclear testing helps, it is well worth the effort. What the President’s words will not do is start an arms race. That would require the United States to be a participant, and the Chinese and Russians left the starting blocks long ago.

Understanding President Trump’s Truth Social Post on Nuclear Testing? was originally published on Global Security Review.

For advocates of renewed nuclear weapons testing, stop packing for the journey to the Nevada National Security Sites (NNSS). No mushroom cloud or subterranean detonation is soon to take place. Anti-nuclear protestors should also stay home.

The truth is less exciting. No real changes will happen “immediately” that “light up the sky and shake the ground.” This is not to say that the announcement had no effect. In fact, the statement was indeed monumental and incredibly significant.

Contrary to public perception, the US has never ceased testing its nuclear weapon systems. What has changed since the 1992 self-imposed moratorium on high-yield explosive testing is the nature of those tests.

Before 1992, the US conducted 1,054 nuclear weapon test explosions. The country detonated 839 of those warheads underground, mostly at the then-named Nevada Test Site, where the last halted test, Icecap, still stands as a memorial to the explosive testing days.

Several scientists involved in Icecap acknowledge that, owing to the extensive preparations undertaken, such as instrumentation, computational simulation, analysis, and test rigging, the most significant insights were gained from the limited number of unsuccessful tests. In other words, there is still great confidence in the performance and reliability of the American nuclear arsenal. It is this kind of “testing” to which President Trump’s declaration is likely referring.

Since 1992, testing has been through proxy systems that simulate a nuclear explosion’s unique energy output and then uses the results to validate physics models on advanced computer systems, known as physics-based modeling. This approach provides a way to validate the physics and predict the performance of a nuclear explosion under conditions that were never known in an underground test.

Scientists continuously conduct these tests, improving and refining them as added details are learned. They often report that scientists know much more now than possible from explosive testing.

Despite the president’s directive that testing “will begin immediately,” experts agree that resuming full-scale nuclear explosive testing is a complex and time-consuming endeavor. According to the Arms Control Association, it would take at least 36 months to prepare the Nevada Test Site for contained underground detonations.

This includes environmental assessments, infrastructure upgrades, and political approvals. This does not mean that explosive testing is impossible, but it represents a clear change in policy and a national effort to move nuclear weapons to the forefront of national strategy through an active nuclear explosive testing program.

The phrase “on an equal basis” is particularly provocative. It implies that nations like Russia and China may already be conducting nuclear explosive tests or at least advancing their capabilities in ways that challenge the spirit of the Comprehensive Nuclear Test Ban Treaty (CTBT). Either of these should sound alarms and rightly must elicit a response.

The president has chosen precisely the response as outlined in the National Institute for Deterrence Studies’ (NIDS) Dynamic Parity report, where a response matches the activities of adversaries, giving them the option to continue expanding their nuclear capabilities, knowing how America will respond, or cease and return to the table to negotiate for a more stable relationship.

The announcement of an “immediate” resumption of (explosive) testing is monumental because of its effect on deterrence. In his international policy book, The Necessity of Choice, Henry Kissinger writes that deterrence is the (mathematical) product of will and capability. Few would question that the US has a nuclear arsenal and delivery systems that can cause incredible damage and harm. However, there is growing criticism and concern that the US lacks resolve to deploy its nuclear weapons even if an existential crisis arises.

Without clear signals of resolve, adversaries may doubt American willingness to act, weakening deterrence. This declaration supports that resolve without making a direct threat to any adversary. It simply puts them on notice.

Whether President Trump’s message leads to actual detonations or remains symbolic, it marks a turning point in American nuclear policy. It also aligns with the Dynamic Parity framework advocated by Curtis McGiffin and Adam Lowther, which calls for symmetrical deterrence and strategic clarity.

President Trump is demonstrating resolve, assuring allies, and highlighting American commitment to nuclear deterrence. The path forward should prioritize modernization, transparency, and diplomacy—not a return to the destructive rituals of past decades.

“Resumption of Nuclear Testing”—Not So Fast! was originally published on Global Security Review.

The reality is that Americans live in an increasingly complex threat environment, and the credibility of the nuclear deterrent ultimately depends on America’s ability to respond to technical or strategic surprise. That includes being ready, if necessary, to conduct a nuclear test.

There are multiple and specific conditions under which the US might be compelled to resume underground nuclear testing, each involving serious strategic or technical concerns that cannot be resolved through non-explosive means as directed by the Stockpile Stewardship Program obligations.

From an American strategic perspective, it is possible that a future administration or Congress could determine that the long-standing moratorium on nuclear testing no longer serves American interests. For example, if credible intelligence revealed that an adversary, such as China or Russia, were conducting yield-producing tests, particularly to develop new capabilities or gain strategic advantage, then confidence in the existing deterrence balance could be undermined.

Adversary behavior is a factor the United States cannot ignore. China and Russia maintain active test sites and appear to be positioned to resume testing on short notice. If either nation were to conduct a low-yield test that altered the strategic balance, the US would need to respond—not necessarily by testing, but by demonstrating that it is able. Detecting and interpreting data from these tests may result in the restoration of confidence in the status quo.

Should a nuclear-armed adversary employ or threaten limited nuclear use, a carefully calibrated test could be used to demonstrate resolve, reassure allies, stabilize the situation, and deter further escalation. Such signaling would carry substantial diplomatic consequences and would only be contemplated under extraordinary circumstances.

In addition to strategic drivers that might lead to the resumption of nuclear testing, various technical issues might force America’s hand. For instance, the inability to certify the stockpile through the Stockpile Stewardship Program, such as technical issues with weapons or their components, might also be a driver to resume full-scale nuclear testing.

One such condition would be the emergence of significant doubt about the reliability or safety of an existing warhead type. As the stockpile ages, performance uncertainties can develop in critical components such as plutonium pits, high explosives, or firing systems. If these concerns cannot be resolved through laboratory experiments, modeling, or subcritical testing, a nuclear test might be required to validate performance or ensure safety margins. Such a step would follow a determination by the Nuclear Weapons Council and the national laboratories that non-testing alternatives are insufficient.

A second issue involves the development and certification of new warhead designs. While current policy emphasizes life-extension programs using legacy designs, future geopolitical or technological developments could prompt the US to pursue novel nuclear systems. For example, if the Department of Defense sought a warhead optimized for hypersonic delivery or deeply buried targets, such a design might require full-scale testing for certification—particularly if it deviates from previously tested architectures.

Lastly, there is also the possibility of future weapon development. While current policy focuses on life-extension programs, emerging mission needs may eventually require new designs. If those designs fall outside the range of previously tested systems, the US may have no choice but to test them to certify performance.

Should the United States confront a situation where confidence in warhead reliability or safety can no longer be assured through non-explosive means, or where geopolitical developments erode the credibility of deterrence, a timely and technically sound return to testing may become necessary. However, should the US resume testing for any reason, a great number of challenges will need to be met and overcome.

During the four decades of active nuclear explosive testing, the US developed a strong and thorough testing infrastructure and mindset. As nuclear explosive weapon technology evolved, so did the methods of executing tests and measuring the performance of devices. Facilities, mostly in Nevada, were built and staffed to provide an environment capable of supporting test activities and all the personnel required to perform the tests.

These tests required the expertise of scientists from multiple disciplines, engineers of various specialties, program managers, environmental control technicians, and a wide array of support staff. In addition to the technical workforce, entire teams were responsible for sustaining day-to-day life at remote test sites—providing essential services such as food, water, housing, sanitation, medical support, and logistics.

A rough estimate of the numbers of personnel required to execute an active testing program can be found in a 1981 Department of Energy Nevada Operations Office Newsletter. There were 240 federal employees, 7,100 contractors (laboratory and university personnel), and 11,300 southern Nevada support jobs. Unfortunately, just bringing together the wide variety of personnel needed to execute and support testing is only meeting an obvious challenge. A more subtle challenge is relearning how to keep any explosive test from eaking out of the ground and into the atmosphere.

A resumption of testing would still require the US to meet the obligations of two in-force international treaties; the Threshold Test Ban Treaty (TTBT), which limits the explosive yield of any test to 150 kilotons (kt), and the Limited Test Ban Treaty (LTBT), which bans all above ground and underwater tests. Compliance with the 150 kt limit on explosive yield can be easily maintained because scientists from the national laboratories can confidently ensure the magnitude of the yield will not exceed the limit.

Compliance with the obligations of the Limited Test Ban Treaty presents a different challenge. The cadre of scientific, engineering, and technical experts who would conduct the test are unlikely to have ever faced the challenges of nuclear testing—ensuring the energy and radioactive debris is “contained” in the underground environment.

The cadre of experts who last tested a nuclear weapon, almost 35 years ago, had to “learn” how to meet this unique challenge. Most likely, none of the current cadre has ever been asked to deal with such a large amount of energy released in such a small time increment. Keeping a test contained underground is a vital national interest as a leak of radioactive materials from a nuclear test would cause significant harm to the nuclear enterprise.

Any resumption of nuclear explosive testing would represent a fundamental policy shift with far-reaching implications. A return to testing would affect arms control dynamics, global nonproliferation norms, and the strategic behavior of both allies and adversaries. For these reasons, the threshold for testing remains extraordinarily high, but it is not absolute. Given the challenges facing the United States, dramatic change may come when least expected. A requirement to test a nuclear weapon for strategic or technical reasons may be a part of that change.
