This family must not be abandoned. I remember that back in the days of the first intifada, a little Bedouin girl was accidentally injured by the IDF. Back in those days the State of Israel not only apologized for having caused the little girl's injuries which resulted in permanent blindness. There was also restitution made. The State of Israel provided the little girl with a "dunya" (dowry). The dowry included several taxi licenses and the provision of taxis for the man who would marry her.
I do believe that the State of Israel must act in a similar manner here.
The State of Israel must provide for this man's widow and her children. It is the correct thing to do, it is the just thing to do. We should just do it.
