Are you surprised? Did you need to know this?

By "this" I mean the report that the U.S. has been conducting spying in Iran. I would have bet we were before this report, and I'd have been pretty upset if we hadn't. Why is it such a big deal? Does Reuters really think that this is a shocking irregularity? Or does it just think it will embarrass the Bush administration, who will have no comment to affirm or deny it?
