I guess what they say about military intelligence is self paradox, not even the Patriot anti-air defence missile works, they claim �out of 42 missile attacks on Israel during the golf war, 41 defence patriot has successfully launched and intercept the target missile.� But the truth was later uncovered, those 41 successful intercept does not mean enemy missile destroyed, it means Patriot successfully exploded on the track on the enemy missile, but did not destroy the target. The reason was Patriots are too slow, comparing to the Iraq Scot missiles that never fly in a straight line, it can not be used to defend against the Iraqis. Even during later testing phase, there�s only 0% to 11% of chance that the defence missile actually did hit the �target�, and that target meant pieces of metal that came off the Scot missile. Which was the reason the computer system reported a success. Even the first success testing run that shocked the world was fake, in the night sky the first Patriot exploded on the right spot where the dummy missile would be, but... the truth was there aren�t any missile in the sky that night. Looks like there�s still more we can do to improve the air-defence system, that�s where comp-science comes in :) But I will not trust the newly designed Patriots to work perfectly, so if the war on Iraq starts, Americans better not count on the Patriot to work 90% like what they claim in the beginning.
