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.

For some time, opponents of U.S support for Israel have been urging the White House to end the war in Gaza, or simply calling for a ceasefire. Douglas Feith and Lewis Libby consider what such a result would actually entail:

Ending the war immediately would allow Hamas to survive and retain military and governing power. Leaving it in the area containing the Sinai-Gaza smuggling routes would ensure that Hamas can rearm. This is why Hamas leaders now plead for a ceasefire. A ceasefire will provide some relief for Gazans today, but a prolonged ceasefire will preserve Hamas’s bloody oppression of Gaza and make future wars with Israel inevitable.

For most Gazans, even when there is no hot war, Hamas’s dictatorship is a nightmarish tyranny. Hamas rule features the torture and murder of regime opponents, official corruption, extremist indoctrination of children, and misery for the population in general. Hamas diverts foreign aid and other resources from proper uses; instead of improving life for the mass of the people, it uses the funds to fight against Palestinians and Israelis.

Moreover, a Hamas-affiliated website warned Gazans last month against cooperating with Israel in securing and delivering the truckloads of aid flowing into the Strip. It promised to deal with those who do with “an iron fist.” In other words, if Hamas remains in power, it will begin torturing, imprisoning, or murdering those it deems collaborators the moment the war ends. Thereafter, Hamas will begin planning its next attack on Israel:

Hamas’s goals are to overshadow the Palestinian Authority, win control of the West Bank, and establish Hamas leadership over the Palestinian revolution. Hamas’s ultimate aim is to spark a regional war to obliterate Israel and, as Hamas leaders steadfastly maintain, fulfill a Quranic vision of killing all Jews.

Hamas planned for corpses of Palestinian babies and mothers to serve as the mainspring of its October 7 war plan. Hamas calculated it could survive a war against a superior Israeli force and energize enemies of Israel around the world. The key to both aims was arranging for grievous Palestinian civilian losses. . . . That element of Hamas’s war plan is working impressively.
