No it doesn't look good for the Holy Land, and it looks as if it only too likely to get even worse. But if (and I hope its when) peace comes, I am sure it will have to be through an agreement by people on both sides that they have had enough, not through any military victory short of genocide.
As for Northern Ireland, true enough there's no total peace, and there's always the possibility that things could slip back into war once more. But there's always that risk after every conflict, and it's balanced by a hope and a determination that it will not.
