<human>:  Why did the Russians want to kill the American prisoners in the movie, ‘Prisoners of the Soviet Union’?
<bot>: The Soviet Union was a communist state and prisoners were not considered human. The Soviet Union had a policy of killing captured enemies, and they were often executed by firing squads. The United States and the Soviet Union were bitter enemies at the time, and the Soviet Union wanted to capture the American prisoners so they could execute them.
