The Guardian view on Israel’s booby-trap war: illegal and unacceptable | Editorial

In the second world war, guerrilla forces scattered large quantities of booby-trapped objects likely to be attractive to civilians. The idea was to cause widescale and indiscriminate death. The Japanese manufactured a tobacco pipe with a charge detonated by a spring-loaded striker. The Italians produced a headset that blew up when it was plugged in. More than half a century later, a global treaty came into force which “prohibited in all circumstances to use booby-traps or other devices in the form of apparently harmless portable objects that are specifically designed and constructed to contain explosive material”. Has anyone told Israel and its jubilant supporters that, as Brian Finucane of the International Crisis Group points out, it is a signatory to the protocol?

On Tuesday, pagers used by hundreds of members of the militant group Hezbollah exploded almost simultaneously in Lebanon and Syria, killing at least 12 people – including two children and four hospital workers – and wounding thousands more. This situation is directly analogous to the historical practices that current global arms treaties explicitly prohibit. US media say Israel was behind the attack, and the country has the motive and the means to target its Iran-backed enemies. Israel’s leaders have a long history of carrying out sophisticated remote operations, ranging from cyber-attacks, suicide drone attacks and remote-controlled weapons to assassinate Iranian scientists. On Wednesday it was reported that Israel blew up thousands of two-way personal radios used by Hezbollah members in Lebanon, killing nine and wounding hundreds.

This week’s attacks were not, as Israel’s defenders claimed, “surgical” or a “precisely targeted anti-terrorist operation”. Israel and Hezbollah are sworn enemies. The current round of fighting has seen tens of thousands of Israelis displaced from the Israel-Lebanon border because of the Shia militant group’s rocket and artillery attacks.

However, the pager bombs were clearly intended to target individual civilians – diplomats and politicians – who were not directly participating in hostilities. The plan appeared to produce what lawyers might call “excessive incidental civilian harm”. Both these arguments have been levelled at Russia to claim Moscow was committing war crimes in Ukraine. It’s hard to say why the same reasoning is not applied to Israel – apart from that it is a western ally.

Such disproportionate attacks, which seem illegal, are not only unprecedented but may also become normalised. If that is the case, the door is opened for other states to lethally test the laws of war. The US should step in and restrain its friend, but Joe Biden shows no sign of intervening to stop the bloodshed. The road to peace runs through Gaza, but Mr Biden’s ceasefire plan – and the release of hostages – has not found favour with either Israel’s prime minister, Benjamin Netanyahu, or Hamas.

The worry is that Israel’s actions lead to a disastrous all-out conflict that would pull the US into a regional fight. The world stands on the edge of chaos because Mr Netanyahu’s continuing hold on power and consequent insulation from corruption charges depend largely on his nation being at war. None of this is possible without US complicity and assistance. Perhaps it is only after its presidential election that the US will be able to say that the price of saving Mr Netanyahu’s skin should not be paid in the streets of Lebanon or by Palestinians in the occupied territories. Until then, the rules-based international order will continue to be undermined by the very countries that created the system.
