Turkish PM Erdogan has apologized, in a way, for the killing of a million Armenians.

He did not use the term "genocide" but at least recognizes that the killing was wrong. It is a step forward.

This is not a matter of personal blame. I expect that none of the people who decided how Turkey would treat the Armenians is still alive today. The point is that states need to acknowledge their wrongs in order to avoid repeating them.
