Armenian Genocide Debate Archives updated and new German Archival sources added |
Yes, officials could try to rewrite history, and sometimes they do. Sometimes they try to write history while it is happening and use propaganda to create nationalistic feelings against their enemies.
German Consul Walter Rossler however, was not very pleasant when speaking to the German government about the Turks. If you read some of his writings however, you can see that while the Germans are allied with the Ottoman Turks, not all of them think highly of the Turks.
So you can rest assured that Rossler is trying to be as accurate as possible to the German government, to make sure they are informed and make the right decisions.
After World War I, there is no reason/benefit to aid the Turks/Ottomans in any way, for Germany, so I don't think you can argue that the Germans might rewrite history to make the Ottomans look good. There's no benefit to that. And after the shame of the Nazi Holocaust, I don't think Ottoman history was really given much thought in Germany anyway.
So I think it would be logical to find the German archives pretty reliable.
