While Hamas and the Gazan's patience is no doubt tested by many things, they should be reassured by considerable international support, which in turn has a good chance of turning into real action on their behalf. That support though will quickly dissipate if they continue firing rockets into Israel. Israel similarly will gain international support by working with the UN, albeit Israel cannot only work with the UN when it suits Israel.
