You can't criticise one side of the Israeli-Palestinian conflict without doing the same to the other side. If you don't, I dear to say that you are a hypocrite with ulterior motives. You don't need to be particularly, historically well-informed to understand that both sides are lost in a maze, in total darkness.
The killings have been going on for over a lifetime and will continue to do so until the international community are ready to assume full responsibility for the security of the people living in Israel and Palestine. History demands that the international community takes this responsibility.
The Gaza conflict puts us at the end of the road.
