And the Soviets killed thousands of Polish army officers, buried them, Stalin denied knowing of their whereabouts, only for the officers to be dug up by the Nazis and when Poland sought the Red Cross’s help in investigating the matter Stalin cut off diplomatic relations with them. And a few months later the Poles leader died in a plane crash, dealing that country another harsh blow.

Yep Katyn.
