|1952||The Congressional committee concludes that there is no question that the Soviets bear blame for the massacre.

It expresses anger at the disappearance of the first Van Vlietreport and says: "This committee believes that had the Van Vliet report been made immediately available to the Department of State and to the American public, the course of our governmental policy toward Soviet Russia might have been more realistic with more fortunate post-war results." However, Soviet leaders continue to insist that the Polish officers found at Katyń were killed by the invading Germans in 1941.
