America's Greatest Threat: Vladimir Putin

In 2011 he boasted that he could destroy America in 30 minutes. But he knows a nuclear strike would be suicide, so Vladimir Putin chooses more insidious ways to attack. It is an undeclared war that he wages from the shadows. He has been accused of wearing many faces: a ruthless KGB spy who will murder anyone who gets in his way; a con artist who tries to charm world leaders; a master tactician befriending America’s enemies to foil its strategies; and boss of a mafia state that has made him the world’s richest man. He plays by his own rules - which US intelligence call an array of dirty tricks. But who is the real Vladimir Putin? And what is he doing to America? (History Channel)
