There are many Western sources that are the basis of evidence that may surprise many researchers. Both Armenian scholars, Turkish scholars, and Western scholars have used these sources to present a certain viewpoint or conclusion.
However, perhaps if one were to read the sources themselves they would be able to draw a more accurate conclusion of their own.
It is important to note that no matter what the perspective, many political positions on the Armenian Genocide Debate do involve archival material and thus no political position should be persecuted because each side's research is significant and substantial.
Germany an ally of the Ottomans during World War I as the leading nation of the Central Powers, had many communications between diplomats and took meticulous archives of the events that occurred in Ottoman Turkey and they had the most access of any European power.
