Valery Yarynich glances nervously over his shoulder. Clad in a brown leather jacket, the 72-year-old former Soviet colonel is hunkered in the back of the dimly lit Iron Gate restaurant in Washington, DC.

Ground-based sensors would detect that a devastating blow had been struck and a counterattack would be launched.
