North Korea has strongly condemned the US plan to develop a futuristic ‘Golden Dome’ missile defence system, warning it could trigger a nuclear arms race in space. The system, promoted by Donald Trump to counter next-generation threats such as hypersonic and cruise missiles, is viewed by Pyongyang as a provocation that would undermine its nuclear deterrent. North Korea’s foreign ministry described the plan as arrogant and dangerous, while China has called it a threat to global stability, saying the USA is ‘obsessed’ with its own security. Analysts note the system could compel North Korea to advance its missile capabilities. While many experts agree that US defence infrastructure needs updating, critics point to the potential geopolitical fallout and high costs - estimated at up to $500 billion long-term. Strategic tensions over space militarisation continue to grow as nations grapple with balancing national defence and global security.
