The Katyn Massacre (mar 5, 1940 – may 1, 1940)

Description:

[On the offenses of Stalin against the Grand Alliance]..."The offenses included the 1939 Nazi-Soviet Pact, which has extinguished Polish independence, together with the subsequent discovery that the Russians had massacred some 4000 Polish officers at Katyn Wood in 1940 – another 11000 remained unaccounted for. Stalin broke with the Polish government-in-exile in London over this issue in 1943, shifting his support to a group of Polish communists based in Lublin…Because Poles would never elect a pro-Soviet government, Stalin imposed one…As a disillusioned Roosevelt put it two weeks before his death: “[Stalin] has broken every one of the promises he made at Yalta.” (Gaddis 2006, p. 22)
