Experts warn that President Donald Trump's proposed "Golden Dome" missile-defense system may not fully protect the U.S. from foreign threats [1, 2].
The proposal aims to shield the country from missile attacks launched by China, Russia, and North Korea. However, analysts said the system could leave the U.S. vulnerable to large-scale attacks while simultaneously provoking adversaries to develop more advanced weaponry [1, 2].
During a discussion at the Brookings Institution in Washington, D.C., on Wednesday, missile-defense experts detailed the strategic risks of the initiative [1]. Steve Fetter, a professor at the University of Maryland, said that the expansion of such defenses often leads to reciprocal actions from other nations [1].
"If we expand these missile defences further, we can expect additional responses," Fetter said [1].
The timeline for such a massive undertaking is a point of significant concern. Reports indicate that the full implementation of the Golden Dome system could take years or even decades [3]. This prolonged deployment window may leave a gap in national security during the transition period.
While some observers believe the plan could offer security benefits to allies, such as Canada, other experts remain skeptical of its efficacy [3, 1]. The contradiction highlights a divide between those who see the system as a regional security umbrella, and those who view it as a flawed shield against sophisticated state actors [3, 1].
The debate centers on whether a national dome is a viable deterrent or a catalyst for a new global arms race [1, 2]. Experts at the Brookings Institution said that the complexity of modern missile technology makes a perfect defense nearly impossible to achieve [1].
“The Golden Dome may not fully protect the United States and could leave it vulnerable to large-scale attacks.”
The Golden Dome proposal represents a shift toward a defensive-centric security posture, but it risks creating a 'security dilemma.' In international relations, when one state increases its defenses to feel secure, adversaries often perceive this as a threat or a move to neutralize their own deterrents, leading them to increase their offensive capabilities. This cycle could accelerate the development of hypersonic missiles or saturation tactics designed to overwhelm the very system the U.S. intends to build.
