Until the world recognizes that Hamas is committing three war crimes -- targeting Israeli civilians, using Palestinian civilians as human shields, and seeking the destruction of a member state of the United Nations -- and that Israel is acting in self-defense and out of military necessity, the conflict will continue.
In a recent incident related to me by the former head of the Israeli air force, Israeli intelligence learned that a family's house in Gaza was being used to manufacture rockets. The Israeli military gave the residents 30 minutes to leave. Instead, the owner called Hamas, which sent mothers carrying babies to the house.
Hamas knew that Israel would never fire at a home with civilians in it. They also knew that if Israeli authorities did not learn there were civilians in the house and fired on it, Hamas would win a public relations victory by displaying the dead. Israel held its fire. The Hamas rockets that were protected by the human shields were then used against Israeli civilians.
These despicable tactics -- targeting Israeli civilians while hiding behind Palestinian civilians -- can only work against moral democracies that care deeply about minimizing civilian casualties. They never work against amoral nations such as Russia, whose military has few inhibitions against killing civilians among whom enemy combatants are hiding.
