Does America need an Iron Dome also?

Since when have we, the greatest superpower the world has ever known, acquired a persecution complex? The Trump military defense initiative, the Golden Dome, for shooting down a nuclear first strike on the US mainland, is projected to cost taxpayers $175 billion. The Pentagon has been tasked to develop and complete the project, even if it is half-assed, within three years before Trump leaves office in January 2029. It is going to be another feather in Trump's cap regardless of its relevance to Americans' welfare and well-being.
