After a costly cyber attack on Sony Pictures, a look at how the U.S. plans to confront North Korea and the rise of cyber terrorism; how Obama was able to normalize U.S. relations with Cuba and what it will mean for both countries; and will the 2016 presidential election feature, Jeb Bush and Hillary Clinton of America's political dynasties?

North Korea continues its hostile rhetoric and saber-rattling prompting concerns over their nuclear capabilities.  Also, do today’s  job numbers signify a cooling economy? Plus, momentum for new immigration legislation and this week’s political wrap-up. Joining Gwen: David Sanger, New York Times; David Wessel, Wall Street Journal; Fawn Johnson, National Journal; Amy Walter, Cook Political Report.
