Again, we're here to talk NATO. I'm not an expert on the U.S. BMD system so I wouldn't be in a position to provide you any context as to the effectiveness of the system versus evolving missile.... I can't answer that question. I don't have that information.
Some of that perhaps is available in the public domain. I think you may find some of the information on the testing of the system, etc., but I don't have that information, unfortunately.
