The FBI monitored Soviet dictator Josef Stalin’s only daughter after she defected to the United States in 1967, newly declassified documents show, the Associated Press reports.
The documents show FBI agents were gathering information to find out how Lana Peters’ arrival to the U.S. was affecting relations with other countries.
One source said the impact was “profound.”
“Our source opined that the United States Government exhibited a high degree of maturity, dignity and understanding during this period,” according to the memo, the AP wrote. “It cannot help but have a profound effect upon anyone who is considering a similar solution to an unsatisfactory life in a Soviet bloc country.”
Peters lived a relatively quiet life before she died in a nursing home in 2011.
