you would need to deploy thaad. the follow on discussions with the turks, how about accepting a few interceptors. you have to be about 5 kilometers a second to protect united states from a european launch location. if you do get above 5, 5.5, 6 kilometers per second, the problem is you start potentially poseing a threat to russia. you cannot have your cake and eat it to. you can't defend from europe against iranian icbms without potentially encroaching on russian capability. though in my mind you don't encroach on it very much. most of the concerns are political. airborne infrared, space-based infrared, good sensors. you need more than one or two radars and nato radars, by the way, the french are developing radars, germans, others, hopefully they will contribute to the system. multiple radars and rapid control system. i think that's it. yeah. so that's the kind of capability the system could have. there's several key pillars required to really make this thing work fairly well, which i believe it could. >> thanks. >>
