I well recall asking my Mom
( the old Sarge who ended up in Intelligence in WWII )
"Mommy, why did they have to die?"
Her answer to a little child remains with me to this day...
"Son, what they did could kill millions of American civillians..."
The Venona Secrets: Exposing Soviet Espionage and America's Traitors by Herbert Romerstein, Eric Breindel as well as Witness by Whittaker Chambers should be required reading for all high school seniors in the U.S. and a condition of graduation.
Of course, these people never quit and Morton Sobell still denies his part in the conspiracy: My interest in this event is more than academic. I was convicted with Ethel and Julius Rosenberg of "conspiracy to commit espionage" in 1951--a conviction achieved through government-sponsored perjury--and served more than eighteen years in prison. Since I am named twice in the presently released decrypted messages, I am naturally a bit skeptical of pronouncements emanating from our government's law agencies.
May they all rot in hell.
