In a change, the Biden administration is now signaling that it backs an Israeli strike against Iran

"The last time President Joe Biden helped Israel repel an Iranian missile onslaught, he advised Benjamin Netanyahu against retaliation, telling the prime minister to “take the win.”... Jason Brodsky, the policy director at the United Against Nuclear Iran advocacy group, said Israel and the United States were at different points on what he called the “risk clock.” “Israel right now is in a very risk-ready mood but the U.S. is in a very risk-averse move,” he said. “Israel is risk-ready because of the success it’s had in decapitating Hezbollah, and it senses some momentum right now in its operations, and the U.S. is risk-averse because we’re on the verge of a presidential election.""
