No Alternative to Ballistic Missile Defense in Central Eastern Europe
It seems there's no alternative to ballistic missile defense in central Eastern Europe.

NATO’s layered ballistic missile defense (BMD) is part of the Alliance’s response against the increasing threat posed by the proliferation of ballistic missiles and changes in the political climate. In central eastern Europe (CEE) a key component of this system—capable of eliminating a limited ballistic missile attack—is being deployed at two bases: in Deveselu, Romania (operational) and Redzikowo, Poland (under construction). Although they are operated by U.S. personnel, they constitute part of the overall NATO system.
