President Trump has announced the Golden Dome missile defense system, designed to intercept missiles globally, with an estimated cost of $175 billion. The initiative, inspired by Israel's Iron Dome, aims to enhance U.S. security against threats from China and Russia. Initial funding of $25 billion is included in a congressional budget bill, with plans for operational capability before the end of Trump's term. Critics, including China, warn that the project could escalate militarization in space and provoke an arms race. The system will involve multiple states and defense contractors, with oversight from Space Force General Michael Guetlein.
