US Missle Interceptor Tests a Success

An anonymous reader writes to mention that the U.S. Missile Defense Agency and Lockheed Martin recently reported success in the test flight of the Terminal High Altitude Area Defense (THAAD) missile system. "THAAD is designed to defend U.S. troops, allied forces, population centers and critical infrastructure against short- to intermediate range ballistic missiles. THAAD comprises a fire control and communications system, interceptors, launchers and a radar. The THAAD interceptor uses hit-to-kill technology to destroy targets, and is the only weapon system that engages threat ballistic missiles at both endo- and exo-atmospheric altitudes."

      That may have been true with respect to Mutually Assured Destruction, but I think that this is aimed more at modern asymmetrical warfare. These days the US doesn't really fear massive barrages from the Soviet Union or China as much as it fears a single missile from North Korea or Iran with a nuclear warhead. Something which can inflict tens of thousands of casualties.

      Response to such an event would be difficult. To prevent it from happening again we'd have to inflict massive, disproportionate damage on the enemy, thus incurring truly epic international hatred. We wouldn't even be 100% certain of being able to identify the enemy.

      This throws the balances of MAD out of whack. I can actually believe North Korea would try such a thing and believe they could get away with it. It knows that the first thing China would do is insist that the US take no retaliation, and back it up with real MAD. Shooting down that one missile (or at least making North Korea believe we could) dramatically reduces the risk.

      (Note: I'm not an expert in international relations. There are plenty of people who would say that the US is busily making the world a more dangerous place, and has been since before our latest Iraq debacle.
