Is it self-defense to kill women and children, to ruin and bulldoze mud houses of Palestinians?

I invite the world conscience to do a judgment… The fact is that a nation is being humiliated, arrested and killed in its homeland; its youth are being taken away, the security of their lives, properties and houses is being threatened by the occupiers of the same land. Now, the world conscience is to do a judgment and say who is right here and what is the duty of the human beings?…The U.S. President is defending the actions of the Israeli occupier regime and says that Israel is defending itself! Israel is doing these massacres while he says that Israel is defending itself and considers its actions as a fight against terrorism! Is it self-defense to kill women and children, to ruin and bulldoze mud houses of Palestinians?
