With a bit more googling around Meir Sheetrit, the cabinet minister who made the demand I came upon a more informative article on 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."Zionists are fond of whining that demonising Israel is antisemitic but what about when Israel demonises itself in this way? Is that antisemitic? When a state's ministers can call for the eradication of whole towns no words of denunciation could be considered too strong, in fact I can't think of any words that would be strong enough.
