In 1951 and 1952, with the Korean War as a background, a congressional investigation chaired by Rep. Ray Madden and known as the Madden Committee investigated the Katyn massacre. It concluded the Poles had been killed by the Soviet NKVD and recommended the Soviets be tried before the International Court of Justice. However, the question of responsibility remained controversial in the West as well as behind the Iron Curtain. In the United Kingdom in the late 1970s, plans for a memorial to the victims bearing the date 1940 (rather than 1941) were condemned as provocative in the political climate of the Cold War. It has also been alleged that the choice made in 1969 for the location of the Byelorussian Soviet Socialist Republic war memorial at the former Belarusian village named Khatyn, the site of the 1943 Khatyn massacre, was made to cause confusion with Katyn. The two names are similar or identical in many languages, and were often confused.
