This has turned into revenge begets revenge and only, only these two countries will be able to stop this violence. Both sides have to change drastically but they must decide when. They must respect that both sides have the right to live in peace. I don't think the UN nor any other entity can force them to stop and work for peace.
I am not saying that the deaths don't bother me, because they do very much. I would like to take both sides (leaders) lock them in a room with no windows, no water and no food until they come to a viable solution, but I can't .
