“The Americans”: Lots of things can destroy a carefully planned spy operation. Misplaced loyalties, infiltration and even dumb luck are expected. But what happens when an asset’s emotions are compromised. In “Comint,” the KGB stands to lose all missile-defense information because one man can’t move past the death of his beloved wife. And the spies can’t offer needed emotional support with the FBI watching. (Also, if you want to get valuable and classified information out of the FBI, buy your source a pair of fancy pumps.)
