Faced with the intense difficulty of what to say about Ariel Sharon, the former Israeli prime minister who died early Saturday after eight years in a coma, President Barack Obama didn’t say much. The statement from Obama — who never met Sharon, and wasn’t yet even running for president when he fell into a coma, mentioned nothing about the Israeli leader’s own complicated history with war and peace, remarking only in sending “our deepest condolences” that he was a leader who “dedicated his life to the State of Israel.”
