Scoop: THIS WEEK on ABC - Sunday, November 18, 2012

On Sunday THIS WEEK analyzes the Middle East on the brink of war, the high-stakes talks over the fiscal cliff hanger, and the fallout from the Petraeus sex scandal and the battle over Benghazi: Just one week after his re-election, President Obama faces a widening circle of contentious issues. Will a fresh conflict between Israel and the Palestinians in Gaza escalate into a wider crisis in the region? Can the White House and Congress negotiate a compromise over cutting spending and raising taxes on the wealthy, or will the looming fiscal cliff arrive without a deal? Will there be further fallout from the sex scandal involving former CIA Director Gen. David Petraeus, and will his testimony on Capitol Hill answer lingering questions over what happened in Benghazi, Libya? In her first Sunday morning interview since the election, House Democratic leader Nancy Pelosi, D-Calif., discusses the latest on the fiscal cliff negotiations following Friday's White House summit, only on "This Week." Plus, House Homeland Security Committee Chair Rep. Peter King, R-N.Y., and Senate Armed Services Committee Chair Sen. Carl Levin, D-Mich., debate the Petraeus affair, the ongoing Benghazi investigation and the surging violence in the Middle East.

Then, the "This Week" powerhouse roundtable debates all the week's politics with House Democratic Caucus vice chair Rep. Xavier Becerra, D-Calif., former House Speaker Newt Gingrich, and ABC News' George Will, Donna Brazile and Jonathan Karl. As talks over the fiscal cliff begin, can Democrats and Republicans finally begin working together to solve the looming fiscal challenges, or will stalemate still rule in Washington? Will the ongoing investigations into the Petraeus sex scandal and the attack in Benghazi impact President Obama's cabinet selections for his second term? And will violence in the Middle East grow into a wider war? The powerhouse roundtable debates those topics and more, Sunday on "This Week."
