President Donald Trump has unveiled an ambitious defense initiative called the 'Golden Dome,' a next-generation missile defense system aimed at protecting the entire United States from global threats. The system will rely heavily on space-based technology to detect and neutralize ballistic, hypersonic, and cruise missile attacks, with a projected cost as high as $542 billion over two decades. The Golden Dome marks a significant escalation in America's defense strategy, drawing inspiration from Israel's Iron Dome but designed for a much larger and diverse battlefield that spans both land and space.
