The Pentagon’s Missile Defense Agency Has a Bold New Plan for Protecting America. What’s ‘Plan B’ if it Doesn’t Work? (excerpt)
(Source: Forbes; issued May 28, 2020)
Of all the missions assigned to America’s military, none has a more tortured history than missile defense of the homeland. In the 60+ years since Russia first proved it could launch intercontinental ballistic missiles—ICBMs—many, many ideas have been funded for defending the nation against them.

Most of the ideas did not work out. Politics played a part, but the biggest issue was doubt about whether missile defenses could function effectively in the midst of a nuclear war. That doubt focused mainly on the performance of interceptor missiles developed to engage and destroy incoming nuclear warheads.

Ballistic warheads hurled over intercontinental distances are tough targets to intercept. They are difficult to track and hardened against shock, traveling at hypersonic speeds of up to seven miles per second. If the attacker is reasonably sophisticated, the warheads may be accompanied by “penetration aids” like decoys designed to confuse defenders.

The challenge of destroying hundreds of such warheads in a few minutes during a major missile attack is so daunting that U.S. policymakers gave up long ago. Today, Washington relies on the threat of retaliation to deter Russia or China from launching their long-range missiles.

The assumption is that leaders in Moscow and Beijing aren’t crazy, and therefore won’t launch knowing that such aggression will bring down a rain of nuclear destruction on their countries.

In the case of North Korea, though, we aren’t so sure. Ditto for a future nuclear-armed Iran. The leaders of those nations may not be deterrable in some circumstances.

So, the main thrust of work at the Pentagon’s Missile Defense Agency is to defend against relatively small missile attacks originating in such rogue states. (end of excerpt)
