Trump challenges, Putin roars back: Are we hours, days, or weeks away from Russian nuclear test?

Russian President Vladimir Putin has instructed his senior officials to prepare proposals for potential nuclear weapons testing, following U.S. President Donald Trump’s recent announcement that Washington will resume nuclear testing. It remains uncertain whether Trump’s remarks refer to full-scale live detonations or routine reliability tests of warhead delivery systems, such as the unarmed Minuteman III Intercontinental Ballistic Missile test conducted earlier today.
