When you ahve a cycle of atrocity it may sometimes be possible to identity one incident from one side whiuch started it, but aftrer it's been going on for a couple of generations that ceases to be too relevant.

Imagine this was a vendetta, which in a sense it is. At the root of it from one point of view there would be a particular act of violence by people on one side against people on the other; but dig down past thta root and there will always be other disputes and grievances that led up to that.

Unravelling history like that might make sense as part of some kind of process of truth and reconciliation, in which each side would concentrate its attention on its own atrocities againstvthe other side.

Maybe that'll come about in time, and maybe there are things people can do about it at present. (I believe there were some people working along those lines at one time.) But at present it seems to me the main focus should be on what is happening at the present, and stopping the killing and destruction that is taking place which makes things worse, and leads to more killing and desruction. That was what Rachel was trying to do.
