State of emergency in Gaza

With enormous losses of life on both sides, the Islamist Hamas fighters are taking control of Fatah strongholds in the Gaza Strip, and the conflict appears to be spreading to the West Bank. If the president Mahmoud Abbas is literally overrun, will the world at large, and Israel in particular, simply sit on the sidelines and watch what is happening? Some observers might be tempted to ask: "If the Palestinians have decided spontaneously to murder one another, then why intervene?" I'm convinced that the people of Israel will never think that way. I cannot believe that the Israeli government will accept bedlam in Gaza. Inevitably, if necessary, there will be intervention. To what extent can there be meaningful intervention, however, in a territory that is already totally out of touch with human and social realities?
