Robinson Meyer writes: Lately I’ve been thinking back to something that John Kerry told The Atlantic’s editor, Jeffrey Goldberg, earlier this year. Asked about the importance of the Middle East to the United States, Kerry answered entirely about the Islamic State.

“Imagine what would happen if we don’t stand and fight [ISIS],” he said:
