The “Proportionality” of Israel’s Self-Defense

As usual, the outbreak of fighting between Israel and Hamas has brought forth accusations about the IDF’s use of “disproportionate” force. Most of these criticisms are rooted in a misunderstanding of the doctrine of proportionality, which does not require an army to ensure that an enemy’s losses are somehow “proportionate” to its own. Marc LiVecche explains:

[T]he doctrine of proportionality has at its core the requirement to calculate gains and losses, [that is], determining when a particular use of force—whether a weapon or a tactic—is likely to produce more harm than good.

Proportionality does not mean that an assaulted nation can only take precisely that weight in flesh that has been taken from it. It has the right to be sure the enemy’s capacity and resolve to try and take more flesh in the future has been humbled. There are limits to this, and it seems pretty clear that Israel is doing an appropriate job in keeping them. . . . Meanwhile, Hamas’s attempt to kill anything Jewish without regard for combatant status continues. That their rockets kill Arabs—both inside Gaza and in Israel—doesn’t seem to matter to them. Israel appears to take greater pains in preventing Palestinian civilian deaths than Hamas does.

It should also be remembered that Hamas can make it all stop in an instant, they need only renounce the violence and credibly stand down. To riff on the old truism, if Hamas were to lay down its arms, there would be no more violence. If Israel were to lay down her arms, there would be no more Israel. In proportion to that fact, Israel should continue to fight accordingly.

As the IDF Grinds Closer to Victory in Gaza, the Politicians Will Soon Have to Step In

July 16 2025

Ron Ben-Yishai, reporting from a visit to IDF forces in the Gaza Strip, analyzes the state of the fighting, and “the persistent challenge of eradicating an entrenched enemy in a complex urban terrain.”

Hamas, sensing the war’s end, is mounting a final effort to inflict casualties. The IDF now controls 65 percent of Gaza’s territory operationally, with observation, fire dominance, and relative freedom of movement, alongside systematic tunnel destruction. . . . Major P, a reserve company commander, says, “It’s frustrating to hear at home that we’re stagnating. The public doesn’t get that if we stop, Hamas will recover.”

Senior IDF officers cite two reasons for the slow progress: meticulous care to protect hostages, requiring cautious movement and constant intelligence gathering, and avoiding heavy losses, with 22 soldiers killed since June.

Two-and-a-half of Hamas’s five brigades have been dismantled, yet a new hostage deal and IDF withdrawal could allow Hamas to regroup. . . . Hamas is at its lowest military and governing point since its founding, reduced to a fragmented guerrilla force. Yet, without complete disarmament and infrastructure destruction, it could resurge as a threat in years.

At the same time, Ben-Yishai observes, not everything hangs on the IDF:

According to the Southern Command chief Major General Yaron Finkelman, the IDF is close to completing its objectives. In classical military terms, “defeat” means the enemy surrenders—but with a jihadist organization, the benchmark is its ability to operate against Israel.

Despite [the IDF’s] battlefield successes, the broader strategic outcome—especially regarding the hostages—now hinges on decisions from the political leadership. “We’ve done our part,” said a senior officer. “We’ve reached a crossroads where the government must decide where it wants to go—both on the hostage issue and on Gaza’s future.”
