Current polling has some 90% (!) of Israelis supporting Netanyahu.
Meanwhile Egypt, Jordan, Saudi Arabia, and the United Arab Emirates have basically lined up against Hamas and so aligned themselves with Israel.
Support at home and from the usually hostile neighbors will give Israel a lot more leeway to act. The New York Times reports on this and complains that Egypt, et al's choice is making everything worse by impeding a ceasefire. You know, ceasefires would probably be more feasible if Kerry weren't an idiot, Hamas didn't consistently break them by refusing to stop firing rockets, and - let's be brutally honest - they didn't help the aggressor.
