Perhaps in the eyes of a pessimist. But the fact is there have been plenty of incremental gains (see Patriot missile, tests over the Pacific) and as technology and science continue to advance so does the eventual reality of this program. And when one considers the risk/reward of this initiative it is clear that it can be a multi-billion proposition. I'm thankful that it appears unlikely that the President and the Congress will ever take your narrow view of the program.Originally Posted by M2
