Most countries go through several stages, especially countries that have very tumultuous histories. When certain leaders rule they tend to do horrible things. What those leaders do are not the responsibility of future leaders. You have to attach blame to whoever is at fault, not the current leaders. The buck does not need to be passed if there is no reason to pass it.
History has a funny way of rearing up it's ugly head and holding generations accountable for the sins of the past. But that doesn't make it right. If my father commits murder, is it my responsibility to pay restitution to the widow? Horrible things happened around the globe to many nations and peoples, and in many cases it's the current generation that is paying restitution for the sins of our ancestors. I think it is all a part of the generation that feels it is entitled to more than it's fair share of the crop.
Yes, the genocide was committed by past generations and it often seems unfair to expect people now to pay for the sins of the past. In America, we see a similar issue when we deal with issues like affirmative action. Many people feel like slavery, racism and sins of the past should not be paid for by a current generation. The problem is that those sins of the past tend to have consequences in the present. Certain groups of people still suffer due to the torturing of their ancestors. The question is, how do we make things right for everyone now?
This genocide was committed by The Ottoman Empire and not the current government of Turkey and while acknowledgement is the obvious issue, the hidden issue is all about reparations. In cases such as this, which is not too different from the United States' version of slavery, if you want the real answer, then follow the money.
