Another article about this quote from YNET:
Interior Minister Meir Sheetrit suggested obliterating a Gaza neighborhood in response to Saturday's Qassam fire on Sderot, saying "any other country would have already gone in and level the area, which is exactly what I thing the IDF should do – decide on a neighborhood in Gaza and level it."More >
Israel, he added should provide residents with due warning: "We should let them know 'you have to leave, this area will be taken down tomorrow' and just take it down – that will show them we mean business. Sporadic actions are good," added Sheetrit, "but they're not good enough."
