“...I would expect ‘Gazans’ to dig up those pieces to eat...”
Maybe on the short term. But the US and Europe have been stuffing billions of dollars into Hamas during the past ten years with which modern towns have been built with up-to-date schools and hospitals, fancy restaurants and much “humanitarian” aid.

But no more, Israel with their IDF are taking care of business.
