Opponents complain that we shouldn't "weaponize" space. But that ignores the simple fact that space is already weaponized. After all, if a country fires a long-range missile, that missile has to pass through space. So it only makes sense to place platforms up there to destroy missiles before they can re-enter the atmosphere and threaten Americans.
We already have some of the technology in place. Until the Clinton administration cancelled the Brilliant Pebbles program, it was making great strides. That program can and should be revived and expanded, so we can begin testing and deploying effective space-based interceptors as soon as possible.
Twenty five years ago this week, President Ronald Reagan vowed to "end our long neglect of strategic defenses." Since then, though, we've taken only small steps. We're not defenseless -- our missile system has passed several tests. And last week, the military activated a high-powered radar outpost in Japan to help it track ballistic missiles in that region.
But with nuclear technology in the hands of unstable regimes, we're not as safe as we should be. We'd be crazy -- MAD, even -- not to deploy a layered defense screen that can protect all Americans.
