President Trump has proposed building an antimissile “golden dome” around the United States. But do cinematic spectacles actually enhance national security?

The administration of United States President Donald Trump has circulated plans for its $175bn “Golden Dome” missile defence system, revealing a possible new missile field in the Midwest and details of the project’s plans to shoot down missiles in space, the Reuters news agency reports.

WASHINGTON, Aug 12 (Reuters) - The Trump administration's flagship Golden Dome missile defense system will include four layers -- one satellite-based and three on land -- with 11 short-range batteries located across the continental U.S., Alaska and Hawaii, according to a U.S. government slide presentation on the project first reported by Reuters.
