The complication is that Mr. Snowden did more than that. He also pilfered, and leaked, information about a separate overseas NSA Internet-monitoring program, PRISM, that was both clearly legal and not clearly threatening to privacy. (It was also not permanent; the law authorizing it expires next year.) Worse — far worse — he also leaked details of basically defensible international intelligence operations: cooperation with Scandinavian services against Russia; spying on the wife of an Osama bin Laden associate; and certain offensive cyber operations in China.
