After Iran’s attack on Israel, the world must act: this is a crisis that threatens us all | Simon Tisdall

Netanyahu wanted a wider conflict, and Tehran has walked into his trap. The major powers must immediately head this off

The missiles and drones that rained destruction on Israel in the early hours of Sunday morning have given Israel's prime minister, Benjamin Netanyahu, what he's always craved - a mandate and justification for openly attacking Iran, a country he has long viewed as Israel's archenemy and possible nemesis. The pressing question, which may be answered within hours, is what form Israel's promised significant response" will take - and whether Iran, in turn, will strike back again. We will build a regional coalition and exact the price from Iran in the fashion and timing that is right for us," said the Israeli minister Benny Gantz, as the Israeli war cabinet met to discuss Israel's response today.

It is incumbent on the US, Britain and other friends and allies of Israel to inform Netanyahu in plain terms that continued military, diplomatic and political support is conditional on a legitimate and proportionate Israeli riposte. It would be preferable if Israel did not hit back at all. Iran failed in its apparent aim of inflicting serious harm. Israel says 99% of its missiles and drones were destroyed. Thankfully, casualties have been light. Tehran now says, a little hopefully, that the episode is concluded" - but vows to fight back if attacked.
