Trump's Space-Based Missile Defense Initiative 'Dôme d'or' Faces Cost and Feasibility Challenges

DEFENSE

The proposed 'Dôme d'or' missile defense system, aimed to be deployed by the end of Trump's term, has an estimated cost of $175 billion, with projections suggesting it could exceed $1 trillion over a decade. The initiative intends to place thousands of satellites in low Earth orbit to detect and intercept enemy missiles, significantly altering U.S. military strategy and increasing militarization of space.

Critics argue the plan could destabilize international security and is based on unrealistic expectations. Current U.S. missile defense capabilities, primarily designed to counter threats from North Korea, lack the capacity to effectively address potential attacks from China and Russia, which are enhancing their nuclear arsenals. A robust 'Dôme d'or' could cost up to $3.6 trillion over 20 years, raising concerns about its feasibility and effectiveness, especially given a historically low success rate of missile interceptors.
