As Israel and the United States continue their war with Iran, even promising to assassinate the new and hardline ayatollah, Pope Leo has emerged as a champion of international law. He’s called for an immediate ceasefire. 

Tens of millions of people maybe hearing him, but does the leadership in Jerusalem, Washington and Tehran care? 

Leo understands the brutal history of Iran’s regime, but he’s worried about the strongest nations behaving as they choose, without restraint. 

What balance is he trying to strike?
