I have never read Albert Wass, I have only heard that he was a biased writer. It does not neccessary mean that, he wrote simply untruth. I am sure there are documents about nasty happenings on the other side as well. Such a conflict between two nations surely cause atrocities in both side.

The challenge here, is how to write a neutral article! Therefore mutual actknowledgement of atrocities would be just enough. I would fear to go into details, it would just provoke sentiments.
