Kenny, and KB,
please read very carefully these sites:
Armenian Genocide
Introduction to Armenian Issue - FORSNET
please try to see whole the picture,
by the way if you check the Turkish thesis you can see that the neutrality of these witnesses is highly questionable.
a "Great Armenia" inure to the benefit of almost all western states at these days. so supporting Armenians is very normal. but remember even British cant find any proves to judge the Turks which held in MALTA as prisoniers.
check British archives, theres a letter about "no evidence about a massacre against these Turks"
