While journalists and activists continue to discuss the Gaza war as if it is an unparallelled atrocity, John Spencer—a combat veteran and one of America’s leading urban-warfare experts—concludes that the IDF’s campaign is without parallel for a very different reason.

Israel has taken more measures to avoid needless civilian harm than virtually any other nation that’s fought an urban war. . . . [O]ne of the best ways to prevent civilian casualties in urban warfare is to provide warning and evacuate urban areas before the full combined air and ground attack commences. This tactic is unpopular for obvious reasons: it alerts the enemy defenders and provides them the military advantage to prepare for the attack. The United States did not do this ahead of its initial invasion of Iraq in 2003, which involved major urban battles to include in Baghdad. It did not do this before its April 2004 Battle of Fallujah (though it did send civilian warnings before the Second Battle of Fallujah six months later).

By contrast, Israel provided days and then weeks of warnings, as well as time for civilians to evacuate multiple cities in northern Gaza before starting the main air-ground attack on urban areas. The Israel Defense Forces (IDF) employed their practice of calling and texting ahead of an air strike as well as roof-knocking, where they drop small munitions on the roof of a building notifying everyone to evacuate the building before a strike.

No military has ever implemented any of these practices in war before.

The editors of the Wall Street Journal rightly call the Biden administration’s new policy an arms embargo. (Subscription required.)

The administration would like to focus on the denial of 2,000-pound bombs, which it says are too destructive. Never mind that a professional force can employ them in a manner that restricts the radius of damage. Mr. Biden is also halting a shipment of 500-pound bombs and holding up Joint Direct Attack Munitions (JDAMs), which convert unguided bombs into precision “smart” bombs. Politico reports that small-diameter bombs are being withheld. The Journal adds that the Biden administration has been sitting on a deal that includes tank shells and mortar rounds.

The message from the White House, in other words, is that Israel shouldn’t have large bombs or small bombs, dumb bombs or smart bombs, and let it do without tanks and artillery too. Now isn’t a good time to send the weapons, you see, because Israel would use them.

But it’s even worse than that: withholding the JDAMs in effect encourages Israel to use dumb bombs in instances when precision weapons would be more effective, and less likely to cause harm to bystanders. And then there is the twisted logic behind the decision:

Defense Secretary Lloyd Austin and other U.S. officials explain that the goal of the embargo—which they present as a “pause” or “review”—is to prevent a wider Israeli attack on the Hamas stronghold of Rafah. This is the terrorists’ reward for using civilians as human shields.

It hasn’t been four weeks since Iran attacked Israel directly, in the largest drone attack in history, plus 150 or so ballistic and cruise missiles. . . . Israel needs to be ready now, and its enemies need to know the U.S. stands behind it.
