The threat to the U.S. posed by these emerging capabilities is broader, more mature and evolving more rapidly than has been reported in estimates by the Intelligence Community. Only the five major nuclear powers have them. No, the Missile Defense System is part and parcel of the American empire. Fearing permanent subordination to the U.S., the Russians have already said that they will respond to any U.S. antimissile system by equipping their missiles with more warheads. Current technology still can't distinguish a nuclear warhead from a decoy balloon.
Interceptors are unable to handle warheads that break up into hundreds of small bombs.
After innumerable failures, last October a missile intercept test was successful. The interceptor supposedly distinguished the target from the decoy. Much Pentagon high-fiving ensued. It turned out, however, that the test was so artificial as to be almost meaningless. The interceptor missile also flew to a pre-programmed position.
