Israel is often criticized for disproportionate response to their terrorist foes. Yet any successful military solution is disproportionate. It is the only humane way to fight a war. A war is not a field game designed to be fair and equal, to minimize the game spread. It is meant to defeat an enemy and eliminate a threat.
If a war was fought ‘tit for tat’ it would go on forever and sustain more casualties than necessary. The parties would slowly bleed, reconstruction would never begin, and no one would invest in and develop anything without some property security. Short term ferocity is the humane way to fight a war.
In Gaza Hamas must be not merely restrained, they must be eliminated. They have shown no interest in peace and the sooner they are eliminated the sooner both sides will be at peace.
The more disproportionate the response the better.
