What gives you the impression that Israel is begging for a truce? From where I see it in Israel (which gives me a good vantage point), Hamas is losing badly from this encounter, and the majority of Israelis would be very angry if we agreed to a truce now unless substantial assurances can be obtained that the missiles will stop for a long time. Hamas doesn't care how many of their people suffer or die, so they think they can wait Israel out. But they're wrong.
