You what works? Identifying the purpetrators, prosecuting and convicting them. If you want to go ultra tough, use Mossad to go after Hamas leadership. Heck, even using precision strikes at Hamas leadership in Gaza wouod be better, regardless of the related colleteral damage and casualties. Israel is not doing any of that
ah, yes, it's that simple, just press the magic button that makes all Hamas disappear and all uninvolved civilians live well and prosper...
To me it seems that if those who care about innocent civilians were more focused on demanding Hamas to surrender and release the hostages promptly would be do more to save lives than constantly criticizing Israel, which gives Hamas hope they can survive this (and do what they did again later on)
