You have literally fabricated a war in order to list more victories for the Rus' against Byzantium. If that isn't biased editing I don't know what is. The "event" you write down as a war victory for the Rus', was nothing more than the signing of the Rus'–Byzantine Treaty of 945. The Primary Chronicle you list as your source, is not a surviving work. It's based on what is thought to have been written by Nestor and can't be confirmed. Why should these writings be valued and considered historicity over Greek chronicles written during the time of happenings? Not only that but there is no information about the war of 941 or another war in 945 listed on that wikipage, and its completely void of any citations/references. Individually, the clashes weren't even wars, as they were slight invasions/attempts to pillage. Every single attempt in this age to plunder Constantinople was repelled, so the Rus' would take it out on peasants in outlying farming communities. Should we dig up every reference of Byzantine warships attacking Rus' interests along the black sea, conjuring them up as "wars" and listing them as victories for the Byzantines? that's asinine.
