In recent days, global attention has focused on the United States’ stance regarding nuclear weapons testing, following statements made by former President Donald Trump and subsequent clarifications from the U.S. government. These developments have sparked concerns and speculation about whether the U.S. is planning to resume full-scale nuclear detonations, a practice it has not conducted since 1992. However, senior U.S. officials have moved quickly to reassure both domestic and international audiences that no such nuclear explosions are planned.
On a Sunday interview with Fox News, U.S. Energy Secretary Chris Wright sought to calm widespread worries by explicitly stating that the U.S. government does not intend to conduct nuclear explosions. Wright explained that the tests being referred to are “non-critical explosions,” which are fundamentally different from nuclear detonations. These tests involve examining the non-nuclear components of nuclear weapons to ensure they function correctly, without triggering an actual nuclear blast.
Wright emphasized that residents living near historic nuclear test sites, such as the Nevada National Security Site, have “no cause for concern” about seeing any mushroom clouds or experiencing the effects of a nuclear explosion. He clarified that these non-critical tests are designed to verify the “appropriate geometry” and setup of nuclear weapons components, ensuring the reliability of the arsenal without resorting to full-scale nuclear detonations.
The need for such clarification arose after Donald Trump posted on his social media platform Truth Social that he had directed U.S. defense officials to “start testing our nuclear weapons on an equal basis” with other major powers. Trump’s comments were widely interpreted as a signal that the U.S. might resume full nuclear testing for the first time in over three decades.
In an interview with CBS’s 60 Minutes, aired shortly after the Fox News remarks, Trump reiterated his stance. When asked if he planned to detonate a nuclear weapon, he responded affirmatively, stating, “We’re going to test nuclear weapons like other countries do.” He accused rivals such as Russia and China of conducting nuclear tests covertly, implying that the U.S. should not lag behind in its testing programs. Trump also mentioned North Korea and Pakistan as countries allegedly continuing their nuclear tests.
However, the claims regarding Russia and China’s recent nuclear testing were swiftly denied by both countries. China’s Foreign Ministry spokeswoman Mao Ning asserted that China remains a “responsible nuclear-weapon state” committed to a self-defense nuclear strategy and has upheld its pledge to suspend nuclear testing. She urged the U.S. to contribute positively to international nuclear disarmament and non-proliferation efforts, highlighting the importance of maintaining global strategic balance and stability.
Similarly, Russia dismissed allegations of nuclear testing, particularly in reference to new weapons systems such as the Poseidon underwater drone and the Burevestnik cruise missile. Kremlin spokesman Dmitry Peskov clarified that any information suggesting Russia had conducted nuclear tests was “incorrect” and should not be interpreted as such. These statements aimed to dispel fears of renewed nuclear testing by the world’s two largest nuclear powers.
Among all nuclear-armed nations, North Korea remains the only country to have conducted nuclear tests since the 1990s, with its last known test occurring prior to a self-imposed moratorium announced in 2018. Despite this moratorium, North Korea’s nuclear program continues to be a source of international tension and concern.
In terms of nuclear arsenals, exact numbers are closely guarded secrets by governments, but independent organizations provide estimates. According to the Federation of American Scientists (FAS), Russia holds approximately 5,459 nuclear warheads, while the United States possesses about 5,177. The Arms Control Association (ACA), another U.S.-based group, offers similar figures, estimating 5,580 warheads for Russia and 5,225 for the U.S.
China, recognized as the world’s third-largest nuclear power, is believed to possess around 600 warheads. Other nuclear-armed states include France with 290 warheads, the United Kingdom with 225, India with 180, Pakistan with 170, Israel with 90, and North Korea with approximately 50. These estimates provide a snapshot of the global nuclear landscape, though ongoing developments may alter these numbers over time.
Notably, China’s nuclear arsenal has reportedly expanded rapidly in recent years. The Center for Strategic and International Studies (CSIS), a prominent U.S. think tank, estimates that China has roughly doubled its stockpile over the past five years and could exceed
