Background on Key Players

Donald Trump, the 45th President of the United States, has recently made headlines with his assertions about nuclear weapons testing. His comments come amidst a broader geopolitical climate where nuclear deterrence and arms control remain critical issues.

Russia: A major global power with a significant nuclear arsenal, Russia has previously conducted underground nuclear tests. The country suspended such tests in 1990, adhering to the Comprehensive Nuclear-Test-Ban Treaty (CTBT), which it has yet to ratify.

China: Another nuclear-capable state, China last conducted a nuclear test in 1996. Like Russia, China has signed but not ratified the CTBT. Both countries have maintained a policy of minimal nuclear testing, focusing on maintaining their arsenals without extensive development.

Trump’s Recent Statements

During an interview with CBS’s “60 Minutes,” Trump stated that the United States would conduct nuclear weapons tests, similar to those allegedly carried out by Russia and China in secret.

“I’m saying that we’re going to test nuclear weapons, just like other countries are doing,” Trump said when asked if the U.S. planned to detonate a nuclear weapon for the first time in over three decades.

He further elaborated, “There are Russian tests, Chinese tests, but they don’t talk about it… These are done at great depth underground, where people don’t know exactly what’s happening.”

China’s Response

On Monday, Chinese Foreign Ministry spokesperson Mao Ning refuted Trump’s claims. She emphasized that China adheres to a peaceful development path, maintains a “no-first-use” nuclear policy, and respects its commitment to suspend nuclear testing.

“China has always adhered to the path of peaceful development, follows the policy of not being the first to use nuclear weapons, advocates a nuclear defense strategy, and respects its commitment to suspend nuclear tests,” Ning stated during a regular press briefing.

U.S. Testing Resumption

Trump announced the resumption of nuclear testing on Thursday via social media, just before entering a summit with Chinese leader Xi Jinping in South Korea.

Russia’s Recent Nuclear Developments

Prior to Trump’s announcement, Russia had disclosed testing a new nuclear-powered cruise missile, the Burevestnik, and a nuclear-powered underwater drone.

Global Context on Nuclear Testing

Besides North Korea, which has conducted several nuclear tests in recent years, no other country has detonated a nuclear weapon for decades. Russia and China last performed such tests in 1990 and 1996, respectively.

U.S. Energy Secretary’s Clarification

Trump’s Energy Secretary, Rick Perry, downplayed the president’s comments on nuclear testing. In an interview with Fox News, Perry explained that the tests in question are not nuclear explosions but rather “sub-critical tests” designed to ensure the proper functioning of various components in nuclear weapons systems.

“I believe the tests we’re talking about now are system tests. These are not nuclear explosions… We call them ‘sub-critical tests,’ which means you’re testing all the other parts of a nuclear weapon to make sure they deliver the right geometry and prepare for a nuclear explosion,” Perry said.
