Since it makes little sense for Russia to be "angered" by a missile defense system, I'm inclined to doubt that its true.
Eastern Europe is a good location for such a system, but better yet would be for it to be built in layers, with part of it based in Turkey or Georgia, or even southern Russia if they decided to get on board.
Israel is an obvious target for a missile strike, so its almost a certainty that part of the system will be based there.
