Russia is engaged in a major buildup of both nuclear and conventional missile defense systems at the same time Moscow is seeking legal limits on U.S. missile defenses, according to U.S. officials.
The Russian military is developing and deploying an array of new and modernized anti-missile interceptors that are part of a strategic doctrine that calls for defending against what Moscow believes to be an increasing threat posed by offensive ballistic missiles, said U.S. officials with access to intelligence reports.
