Mr. Rumsfeld is an outspoken proponent of the US military control of space and the development of offensive space weaponry. Plans for outer space warfare are no longer science fiction fantasies seen only in movies and in secret military documents. Financial Disaster George W's plans for a major tax cut plus massive development of missile defense could add up to bankruptcy for this country. The cost is outrageous and incalculable. It is extremely difficult technically to pull off and has failed test after test.
Simple decoys can confuse the defensive missile.
It won't protect us. A ballistic missile comes with a return address. The Pentagon would know its trajectory and would retaliate with a massive nuclear strike. The NMD violates the Anti-Ballistic Missile Treaty and threatens other existing arms control agreements with Russia. Our allies and adversaries alike are opposed to us building this system because it will lead to anew arms race.
