When the Lebanese militia Hezbollah entered the US-Israeli war against Iran by firing rockets and drones into Israel the day after the conflict began on Feb. 28, officials there saw in the crisis sweeping the region a chance to finally drive the militia, already weakened by a series of setbacks, away from Israel’s northern border. They’ve been loath to give it up.

Ten days later, Israel and Lebanon agreed to their own ceasefire, but Hezbollah was not a party to it and fighting has continued sporadically.
