Even if the Israeli army were to succeed in killing every Hamas fighter to the last man, even then Hamas would win. The Hamas fighters would be seen as the paragons of the Arab nation, the heroes of the Palestinian people, models for emulation by every youngster in the Arab world. The West Bank would fall into the hands of Hamas like a ripe fruit, Fatah would drown in a sea of contempt, the Arab regimes would be threatened with collapse.
If the war ends with Hamas still standing, bloodied but unvanquished, in face of the mighty Israeli military machine, it will look like a fantastic victory, a victory of mind over matter.
What will be seared into the consciousness of the world will be the image of Israel as a blood-stained monster, ready at any moment to commit war crimes and not prepared to abide by any moral restraints. This will have severe consequences for our long-term future, our standing in the world, our chance of achieving peace and quiet.
In the end, this war is a crime against ourselves too, a crime against the State of Israel.
