The historians and experts might do the work, but then Erdogan announce whatever results he wants, regardless of the true result. His hold on Turkish media alone may not be enough, but together with the silence of "patriots" (as seen here) would suffice, yes?
If you really cared about the truth, you'd advocate your gov't opening its archives without demanding anything in return from anyone else, just as the U.S. opened it's Cold War archives without demanding China or Russia do the same thing.
It's unlike a Turk to advocate retreat from the battlefield - or is it?
