:If we're going by the starting quote: "How could it be that the governments of the two great Western democracies knew that a place existed where 2,000 helpless human beings could be killed every 30 minutes, knew that such killings actually did occur over and over again, and yet did not feel driven to search for some way to wipe such a scourge from the earth?", then 1998.  

 :It has been examined since then, and it has emerged – plausibly – that the Allies did "search for some way to wipe such a scourge from the earth"; and that Prof. Wyman had maybe not understood what was in Churchill's memoirs. No doubt new research will emerge, so it is an ongoing debate. We would all agree with Bush's 2008 sentiment, but in 1944 things obviously appeared differently.
