Iran is not building a nuke but they are trying to build a nuclear capability. What is the difference? Leon Panetta says they are not building a nuke. But isn’t that what this is all about? Panetta says they are not building a nuke but then says that Iran building a nuke is the “red line” and the U.S. will not tolerate that. So are they or are they not? Sounds like some people need to get their lie, um I mean their story straight.
