A small group of terrorists, maybe 5,000 or 7,000 against a country of more than 6 million people, have dug and built another city 30 to 40 meters underground, and they have tunnels reaching, if not already penetrating, into Israeli land. These people keep on sending rockets against us. For Israel to fight against them on the ground means a battle from house to house, and it will be a brutal combat -- and that becomes a real problem. If we want to solve the problem, it means that we have to be very cruel, and this is not morally easy to do. Many people can die on both sides.
