Obama attempted to get a clearer view of what Petraeus and Crocker would consider a "end game."
"If the definition for success is so high," Obama said "then that portends the possiblity of us staying for 20 or 30 years."
"If on the other hand we have a messy status quo" that does not "pose a threat," Obama asked "what is an achievable time frame?" - A.B.

1:53 p.m.: The last exchange of the hearing sums up the main themes of the morning
Petraeus reminded Sen. Evan Bayh (D-Ind.) said that Osama bin Laden and his deputy in al Qaeda, Ayman al-Zawahiri, view Iraq as their central front in the war on terror. "That is where we must roll them back," said Petraeus, echoing Republican arguments for maintaining a U.S. combat presence in Iraq.
But when Petraeus reiterated his call for "conditions-based reductions," Bayh, like other Democrats, was skeptical.
"And we don't know when that will be?" Bayh said.
"When the conditions are met," the general responded.
Petraeus and Crocker now go over to the Foreign Relations Committee, where Chairman Joe Biden (D-Del) and Sen. Barack Obama (D-Ill.) await. The hearing starts at 2:30 p.m. The liveblog will resume then.

"Our troops not only want to know we appreciate them, their families and they want to understand how their sacrifice is directly connected with our safety and security here at home," Cornyn said. "Sometimes I think that gets lost in the debates on Capitol Hill. Traveling to Afghanistan, I of course was reminded of what happened in that failed state after the Soviet Union left."
Cornyn and other Republican supporters of the surge have used their questions today to stress the role of the surge in snuffing out al Qaeda in Iraq. -W.A.
