Since Gaza isn't producing it and is getting it for free, anything they get, even if very low quality, is Israel doing something good for Gaza. If Gazans want clean water, maybe they should be manufacturing water plants and tubes and cisterns to store water rather than using those materials for rockets. Gazans suffering like this is their own choice. Maybe after Israel dismantled its Gaza settlements in 2005 in a gesture of goodwill, Gazans should have toned DOWN their violence rather than ramping it UP.
