Israel is restrained.....

A scholarly look at proportionality from the Wall Street Journal.

The track record of many of Israel's most powerful accusers--including China, Russia and the European Union--is not nearly as good at balancing civilian risk against military goals.

China killed hundreds of peaceful Tiananmen Square protestors in 1989. It has for five decades occupied Tibet, slaughtering tens of thousands; and it vows to invade Taiwan if it declares independence. Neither the Tiananmen protesters nor Tibet nor Taiwan has ever threatened to "wipe China off the map."

Russia has fought since 1994 to suppress Chechnya's independence movement. Out of a Chechen population of one million, as many as 200,000 have been killed as Russia has leveled the capital city of Grozny. Chechen rebels pose no threat to "wipe Russia off the map." All of the leading EU countries actively participated in NATO's 78-day bombing campaign against Yugoslavia in 1999. The military goal was to stop Yugoslavia from oppressing its Kosovar minority. NATO bombs and missiles hit Yugoslav bridges, power plants and a television station, killing hundreds of civilians. Yugoslavia posed no threat to the existence of any of the EU countries that bombed it.

Compared with how China, Russia, and the EU have dealt with non-existential threats--and despite the law-flouting behavior of Hezbollah, Iran and Syria--Israel's responses to the threats to its existence have been remarkably restrained rather than disproportionately violent.
