I don't agree with the Bush agenda here. There is no reason to deploy a system at this time.
That's not a problem - we can't deploy anything at this time. We've had one moderately successful test (to the limits of what they were testing for), and several failures. We haven't had one full-fledged successful test, and even a successful test would hardly be evidence that the entire system would work. Besides all that, we hardly have the infrastructure set up to deploy even the rudiments of a beginning of a defense.
I see no problem with continuing to test and develop, but concerns about deployment are moot at this point. (And even if he gets money in the budget for it, it's still a moot point until we actually get something working.)
