Yet Roosevelt, in his blind arrogance, continued to ignore this and many other atrocities by Stalin until the day he died. Stalin killed 5 times the number of Soviets who died in the war.
Only Churchill kept sounding the alarm.
Even worse, the Nuremberg Trials carefully document the "responsability" of the Germans in this massacre, thus absolving Stalin. This is why, BTW, you should think twice before citing these records in any serious historical debate. They are an embarassment. I use it as a litmus test for history books. Quoting the Nuremberg records is akin to quoting witchcraft trials minutes.
