I was speaking about principles of operation- the one-warhead, one-interceptor model is hopelessly outdated. Anything that comes from ex-Soviet technology will likely be a MIRV containing 3 or more independently targeted warheads. Even a single warhead is likely to be accompanied by debris from the launch vehicle which is virtually guaranteed to confuse the most advanced of automatic tracking devices. I'll give them the benefit of the doubt that they can actually make an interceptor which will hit an incoming target; of course, that's not a given, since they've been having a hard time hitting a monolithic target, coming on a known trajectory. The only effective ways to stop incoming ballistic missiles are boost stage destruction (tough, since the boost stage occurs either as a surprise from a mobile launcher or deep within "enemy" territory) and high altitude nuclear detonation, early enough to catch MIRVs before they are too far apart. We aren't pursuing anything along either of those lines.
