Israel has a right and an obligation to respond to Hamas attacks, for all the good it will do. Unless Israel holds talks with Hamas, the situation will remain the same until Hamas recieves better weapons, as is bound to happen in time. The tactics which Israel is using against Hamas are those same tactics which has made Hamas stronger than ever before. It would be far more clever of Israel to steal away the loyalty of the Palestinian people through humanitarian gestures rather than punishing all of Gaza for Hamas actions.
