But it has few friends in the Arab world, and the Arab street has not risen in solidarity. And this time, Israeli leaders are publicly and persistently demanding what they call the 'demilitarization' of Gaza as the price for peace - so that Israel is spared another barrage of rockets like those that fell on its soil in 2008 and 2012 - and are again now.The Gaza conflict has lasted almost three weeks with over 700 deathsIsraeli leaders are demanding the 'demilitarization' of GazaKhaled Mashal -- leader of Hamas political wing -- is against thisIs there a halfway house providing Israel with security guarantees?
