The Israeli government didn't need America to join. If they wanted to kill the ayatollah, they could do it alone. If they wanted to denuclearize Iran, every single expert affirmed that it wasn't a realistic goal, no matter how many allies they had. The net outcome of this war is extremely negative for the United States so far, and scott-free for Israel. Defense commentators had been predicting this Iran war manipulation for decades, and warned US policymakers to oppose it as far as they could. Israeli lobbyists now propose US enlistment laws, such is their need for wanton escalation under Trump: https://www.middleeastmonitor.com/20260903-a-proposal-seeks-...
So, what was the goal? For decades, Netanyahu has used the threat of violence and war to secure his position as prime minister. He campaigned for Yitzhak Rabin's assassination, denied any incitement, and then took his place when he was killed. He's ostensibly corrupt and stands accused of manufacturing crises to enable his political support. His administration spends hundreds of millions of dollars rehabilitating his internationally reviled image. I wasn't born yesterday, you can't ambiguate Likud's history of escalation, assassination and manipulation.
