As battles brew at home and overseas, George Stephanopoulos speaks to Obama senior adviser Dan Pfeiffer, Sunday on "This Week."

As North Korea ratchets up its military maneuvers, threatening to test new missiles and re-start its nuclear program, how serious is the threat, and how will the U.S. respond? Does a disappointing new jobs report, with only 88,000 jobs added last month, signal that the American economy has hit another spring slowdown? And will President Obama's new budget proposal out next week, which includes cuts to Medicare and Social Security, re-set the deficit debate in Washington?

Obama senior adviser Dan Pfeiffer answers those questions and more, Sunday on "This Week."

Then, the "This Week" foreign policy roundtable examines the latest threats from North Korea, with ABC News' chief global affairs correspondent Martha Raddatz, just returned from reporting at the North Korea border; New York Times chief Washington correspondent and author of "Confront and Conceal" David Sanger; Fox News anchor Greta Van Susteren; and ABC News' George Will.

And the "This Week" powerhouse political roundtable tackle all the week's politics, including the battle over the budget and economy, gun control, and immigration, with president and editor-in-chief of The Huffington Post Media Group Arianna Huffington; Nobel Prize-winning economist and New York Times columnist Paul Krugman; former Reagan budget director David Stockman, author of "The Great Deformation: the Corruption of Capitalism in America"; Fox News anchor Greta Van Susteren; and ABC News' George Will.
