I think the part that hurts is that nobody Israeli government has any idea what to do with Palestine and its people after the shooting stops, other than the far right nut jobs calling for expansion of Israeli settlements and de facto ethnic cleansing of the land.
Without a viable strategic end goal other than the destruction of Hamas as a military force and political entity, and a refusal to recognize a Palestinian state, what other conclusion can bystanders reach aside from seeing this war as an effort to destroy or displace the Palestinian people?
