Retired Lieutenant General Robert Gard:

-- The purpose of the surge was to provide an opportunity for progress on political reconciliation of contending Iraqi factions. Do you see any near-term prospects for the necessary compromises?

-- We have undertaken a Sahwa program to arm and pay Sunni factions to provide local security. Do you see any hope for the majority of these 90,000 armed combatants being integrated into the Iraqi security forces or provided meaningful jobs by the central Iraqi government?

-- Do you still hold to your previous position that maintaining peace between and among competing Shia factions in the south of Iraq should be left to the Iraqis?

And the military and national security experts at the Center for American Progress have released a report on the strategic failures in Iraq that ends with a series of questions for Petraeus. The last query on this list is one that is rarely asked in Washington: "Has the quality of life improved for ordinary Iraqis" between 2003 and 2007?

There are no shortages of hard questions for Petraeus. The question is, how far will members of the Senate and the House go in grilling the fellow who has become the chief pitchman for George W. Bush's war in Iraq?
