Why Missile Defense Now Raises the Risk of War

Why It Matters

By reshaping strategic calculations, missile defence may increase the likelihood of broader conflicts, undermining regional stability and global arms‑control frameworks.

Key Takeaways

• Missile defense can encourage offensive risk-taking.
• US deployments may lower perceived war costs for allies.
• Israel's 2025 intercept rate fell to 86%, depleting stockpiles.
• Trump's Golden Dome could trigger security dilemma with Russia, China.
• Overreliance on shields reduces civilian protection and escalates conflict.

Pulse Analysis

Missile‑defence technology has evolved from a deterrent tool into a strategic catalyst. When leaders believe their territories are shielded, they may pursue actions previously deemed too risky, as illustrated by Israel's 2025 air campaign against Iranian sites. The psychological safety net lowers the perceived cost of escalation, prompting pre‑emptive strikes that can spiral into wider wars. This shift challenges the traditional view that missile interceptors merely protect civilians and preserve peace.

The regional implications are stark. In the Middle East, the United States' deployment of Patriot and THAAD batteries under the Trump administration has reinforced the illusion of invulnerability among allies, while simultaneously eroding their own defensive reserves. Israel’s declining interception rate—from near‑perfect coverage in 2024 to 86% in 2025—has left millions of citizens exposed and strained logistics for replenishing interceptor stocks. Such degradation not only endangers civilian populations but also fuels adversaries’ confidence that a decisive strike can overwhelm weakened shields.

Globally, the prospect of a universal U.S. "Golden Dome" raises the specter of a renewed security dilemma. Rival powers, interpreting an all‑encompassing shield as a prelude to first‑strike capability, may accelerate offensive weapon development to preserve strategic parity. This dynamic echoes Cold‑War arms races, where defensive upgrades spurred counter‑measures, heightening the risk of miscalculation. Policymakers must therefore balance the immediate protective benefits of missile defence against its longer‑term destabilising potential, ensuring that security enhancements do not inadvertently sow the seeds of larger conflict.
