For days, Israel’s closest Western allies have pleaded with the country’s wartime government not to risk igniting a wider war by responding too strongly to Iran’s barrage of missiles and drones last weekend. And on Wednesday, the top diplomats from Germany and Britain delivered that message in person to Prime Minister Benjamin Netanyahu in Jerusalem.

But Mr. Netanyahu emerged from those talks resolute that his country would not bow to any outside pressure when choosing its response. He declared before a cabinet meeting that Israel would “do everything necessary to defend itself” and warned the allies that “we will make our own decisions,” according to his office.
