There was no attempt by the book's author to "shift the blame." The author did however find facts that prove that there was involvement in the crimes. That was true of some German officers. Others were passive and some tried to report the crimes but were reprimanded by their superiors.
One book reviewer wrote "A commission on these atrocities, which issued its final report on March 29, 1919, accused Turkey and its allies (the Germans) of using barbarous and illegitimate methods against the Armenian citizens. Again, a committee of jurists in 1920, commissioned by the Council of the League of Nations, concluded that the official order to deport the Armenians en masse "was a violation in international law" (p.l9). Two German generals, Bronsart (on July 25, 1915) and Boemich (on October 3, 1915), who served as members of the military mission in Turkey, are said to be responsible for ordering the Armenian deportation."
Here the reviewer is referring to one or two incidents of deportation not the whole operation which was of course the doings of the Ittihadist Turks (Young Turks). I believe that Ittihadist refers to the Committee of Union and Progress Party, not sure.
I don't think it works out all that clearly since there were many "young" Turks of every political, cultural and social stripe.
Now who would be churning up this stuff? Well, the Brits ~ the ancient Ottoman enemy ~ and the Russians under the Commies.
Speaking of folks who have to account for some genocide, the Russians took Ottoman territories that'd been Turkish for a thousand years and did ethnic cleansing on a grand scale. Millions of people were erradicated, their land taken, and then sold and rented out to Mennonite German farmers.
Not sure anybody wants to get into the assignment of "blame" where the Mennonites look like they were in league with the bad guys.
(Last thing the Nancy woman wants to do is blame her little friends in Russia, but she might bite at a chance to smack down some Protestants.)
