" WARSAW, Poland — Poland and the United States struck a deal Thursday that will strengthen military ties and put an American missile interceptor base in Poland, a plan that has infuriated Moscow and sparked fears in Europe of a new arms race. " http://www.huffingtonpost.com/2008/08/14/us-poland-reach-agreement_n_119053.html The United States have stated the system is intended to counter Iran's potential capabilities, however they have also rejected the Russian offer to station an interceptor in Kazakhstan, closer to Iran and the Middle East. Politics aside, I have two specific questions: 1. From a technical perspective, is Eastern Europe the optimal location for such a system, or does the Russian claim have some truth to it? 2. Once built, how difficult would it be to use this base to fire ground to ground missilies,or in which way could this potentially be used to threaten Russian security?
