Israel is not punishing Gaza for electing Hamas. Israel left Gaza unconditionally and what did she get back? Thousands of rockets and infiltrations for terror attacks. What do you expect Israel to do? Allow Hamas to bring into Gaza even more sophisticated and powerful weponry. Israel's mistake was that she bowed to international pressure to stop the war in Gaza instead of finishing her job and giving a deadly blow to Hamas - a recognised terror organization - nothing morer than that.
