The Russian Federation does not see frowned upon installing this defense system and a few steps from its territory, in those countries that once were part of the Soviet Union, but fears that they are just the beginning of a new NATO expansion to the East to Moscow would mean a unwarranted interference of the United States and its allies right in its own backyard.
Since two years ago, Russia annexed Crimea at its territory and its relations with the United States are cracked and it has created a climate of suspicion and mutual distrust which leads automatically to consider every action as hostile and double purpose. According to the Russians, in fact, the missile shield in Europe’s security is only a mask because the Mk 41 Launcher installed on land can also be used to launch nuclear cruise missiles that can have a range of over 500 kilometers and not just the interceptor missiles that would be used by the shield in case of attack.
The Russian Goverment fears that the new missile system will in the long run weaken the capability of offense of its nuclear arsenal and expose it as a possible first strike; the United States claimed that the new system will be used only in an emergency and that aims only to limit the war potential unstable States in possession of nuclear weapons.
