No - obviously if I had information based on clearances I have or have had in the past, I wouldn't be passing it along. This information is completely independent of any privileged knowledge. But, at some level physics are physics. (As I mentioned earlier...this is not my technical area...but I have a decent feel for it...and countermeasures such as decoys have a tremendous effect on missile defense systems). I don't know how good our system is because I don't have a DoD clearance, but I have an idea of what the theoretical limits are and how easily decoys can fool our systems. Furthermore, the technology is based on technology very similar to patriot missile systems - which have a horrible track record.
However...I see your point. If I don't know for sure, then I probably shouldn't make categorical statements. So - with your point taken...I'll say this...I have a good feeling that our missile defense systems would not be all that effective.
On a similar note though....classified information has a way of hiding otherwise scientifically obvious facts from individuals who cannot research them because of compartmentalization of information. It often happens that people who work around systems know less because they aren't allowed than those who have no clearances but have a very good understanding of the physics (again..that isn't me...I only have a decent understanding of it). It's one of the odd side effects of compartmentalization of classified information.
