In a move that has reignited Cold War tensions and drawn global attention, former U.S. President Donald Trump has announced that the United States will resume nuclear weapons testing after more than three decades of restraint.
The announcement made during Trump&rsquo;s trip aboard&nbsp;Marine One to Busan, South Korea, for trade talks with Chinese President Xi Jinping, marks a dramatic shift in America&rsquo;s defense policy.
&ldquo;The United States has more Nuclear Weapons than any other country. This was accomplished, including a complete update and renovation of existing weapons, during my First Term in office,&rdquo; Trump wrote on social media.
He added, &ldquo;Because of the tremendous destructive power, I hated to do it, but had no choice! Russia is second, and China is a distant third, but will be even within 5 years.&rdquo;
<h3 data-start="1597" data-end="1639">&lsquo;We&rsquo;re Going to Do Some Testing&rsquo;</h3>
Speaking aboard Air Force One on Friday, Trump reaffirmed that the U.S. would move ahead with nuclear testing, while leaving open whether it would include underground detonations similar to those conducted during the Cold War.
&ldquo;You&rsquo;ll find out very soon, but we&rsquo;re going to do some testing,&rdquo; Trump told reporters. &ldquo;Other countries do it. If they&rsquo;re going to do it, we&rsquo;re going to do it, OK?&rdquo;
The statement has been widely interpreted as a strategic signal to nuclear competitors Russia and China, underscoring Washington&rsquo;s intent to maintain military parity amid renewed great-power rivalry.

During a separate trip to Malaysia, U.S. Defense Secretary Pete Hegseth defended the decision, calling the resumption &ldquo;a very responsible way&rdquo; to maintain nuclear deterrence.
&ldquo;We&rsquo;re moving out quickly,&rdquo; Hegseth said, noting that the Pentagon would coordinate closely with the&nbsp;Department of Energy to oversee testing operations.
While details remain unclear, experts suggest the directive could either refer to nuclear-explosive testing, conducted by the National Nuclear Security Administration, or flight testing of nuclear-capable missiles.

If carried out, this would make the United States the first nuclear power to conduct explosive tests since North Korea in 2017, breaking a 25-year international moratorium.
The decision, though couched in the language of national security, revives anxieties reminiscent of the Cold War, when nuclear tests were both deterrents and diplomatic flashpoints.
Trump&rsquo;s assertive stance, echoing his first-term nuclear modernization agenda, has once again reignited debate over America&rsquo;s role in global arms competition and whether deterrence can ever truly ensure peace.
