Morton Sobell told The New York Times that he helped pass to the Soviet Union information about an aircraft gun during World War II when the Soviets were U.S. allies.
Sobell also implicated Julius Rosenberg in a conspiracy that delivered to the Soviets classified military and industrial information. He said Ethel Rosenberg was aware of her husband's espionage but did not actively participate. "She knew what he was doing," he said, "but what was she guilty of? Of being Julius' wife."
He said that information from Rosenberg was of little value to the Soviets, except to corroborate other reports. The Rosenbergs were executed in 1953.
Now I'm all for getting your husband's back, but there really are a few instances when you have to look into your soul and decide whether loyalty to your husband trumps his execrable treason against your nation. At least if you are in any way patriotic or care about your country and fellow Americans.
