Earlier this month, the U.S. announced that it would renew shipments of 500-pound bombs to Israel, but would continue to withhold its larger, 2,000-pound explosives. Its stated reason is that such munitions risk unnecessary harm to civilians if used in the densely populated areas of Gaza where Hamas operates. John Spencer argues that this logic misunderstands how these weapons work, and the nature of urban warfare.
The penetration depth of a 2,000-pound bomb, depending on the kind and whether it must go through concrete, is believed to be from sixteen feet to more than thirty feet. Hamas’s military wing is hidden in more than 400 miles of tunnels, some as deep as 200 feet underground. And to Israel’s north, Hizballah, like Hamas, has spent years digging tunnels deeper and deeper to protect what is believed to be an arsenal of over 100,000 rockets, missiles, and drones. Southern Lebanon is referred to as the “Land of Tunnels” due to the miles of deep buried underground networks.
In other words, the IDF doesn’t use its largest ordinance to cause more extensive damage to a wider area (which would risk greater harm to bystanders), but to penetrate more deeply underground. Moreover, there is little reason to believe using fewer or smaller bombs will really reduce civilian casualties:
In the 1945 Battle of Manila, one of the few battles in military history with parallels to Gaza, General Douglas MacArthur banned the U.S. Army from using bombs for fear of destroying the city and killing civilians. Nevertheless, 100,000 civilians perished and most of the city was destroyed to defeat a Japanese force not even half the size of Hamas in Gaza.
Perhaps most importantly, the careful use of heavy munitions will hasten Hamas’s defeat, the prerequisite for easing the suffering of civilians. There is another possible explanation for America’s reluctance to provide heavy munitions, however: not to hobble the IDF’s efforts in Gaza, where most of its heavy bombing campaign is over, but to deter Israel from going to war with Hizballah.
