Christopher, as I said about Libyan soldiers, the Soviet soldiers who killed the Polish officers were just following orders. They were just obeying their superiors. They didn't ask for the mission of killing Polish officers. Killing Polish officers was not in their job description. They joined the military because they were patriotic. They were serving their country. All criticism toward the Soviet soldiers' actions should be directed at the Soviet government and politicians. It was all Stalin's fault.
NB: I am mocking this position.
