Missile Defense Meets Its Moment

Now America and Its Allies Must Adapt

For decades, missile defense was one of the most divisive issues in national security policy. Supporters argued it would protect civilian populations, reassure allies, and strengthen deterrence. Critics countered that it was too expensive, technically unreliable, or strategically destabilizing. Entire careers were built debating whether missile defense could ever fulfill its promise.

That long-running debate has now been overtaken by events. In Ukraine, Israel, and across the Middle East, missile defense has moved from theoretical concept to operational necessity. It is no longer something discussed only in think tank seminars or academic journals. It is being tested in combat under real-world conditions.

The results are increasingly clear: missile defense works.  Not perfectly—but decisively enough to shape outcomes. It has saved lives, preserved freedom of action for political and military leaders, and complicated the coercive strategies of aggressor states.

The central question now is no longer whether missile defense is worth pursuing. It is whether the United States and its allies can modernize quickly enough to stay ahead of rapidly evolving threats.
