The GBIs of our GMD system employ heat-seeking Kinetic Kill Vehicles. With such a system there is literally no margin for error. We either hit the Russian/Chinese pointy-shaped nuke-carrying re-entry vehicles – which are stone cold when exo-atmospheric – with our heat-seeking bullets or we don’t.
And, of this writing, we have never even tried to hit an exo-atmospheric stone-cold RV with our heat-seeking bullet. We’re having enough trouble hitting artificially hot-hot-hot targets.
So, don’t you feel better already about Condi’s famous diplomatic triumph?
What we have here are systems which are completely untested regarding the manner in which they are actually supposed to work, and prone to catastrophic failure.
