California’s two Democratic Senators responded Thursday to what many see as the impending collapse of the Shiite Iraq government, led by Nouri al-Maliki, by Sunni forces that have overtaken the northern part of the country.

Speaking to reporters at the Capitol, Sen. Dianne Feinstein, D-Calif., the more hawkish chair of the Senate Intelligence Committee, said the Sunni forces are “on the march to Baghdad” and said the consequences “could be devastating.”

Feinstein said she’d like to discuss the situation with the administration “assuming I’m asked to give my views,” adding, “this is a very dangerous situation.”

Both parties in Congress expressed alarm at the apparent collapse of Iraqi government forces, but Republicans generally are condemning President Obama’s decision to withdraw nearly three years ago, while Democrats exhibited a range of responses, from House minority leader Nancy Pelosi’s outright opposition to any intervention, to Boxer’s reluctant embrace of possible action.

“This is not the time for a blame game,” Feinstein said. this is a time for both sides to come together. We’ve lot a lot of people in Iraq…Iraqi’s have lost a lot of people….Whether that’s possible or not, I don’t know.”

Sen. Barbara Boxer issued a statement urging that any U.S. action in Iraq be “well-considered and well-executed in coordination with our allies and the Iraqi government and military.”

“The current crisis in Iraq has its roots in an ill-conceived war that helped to fuel sectarian violence and an Iraqi government that has excluded minority populations from governing,” Boxer said. “Much American blood was spilled during the Iraq War and while I believe we should go after ISIS-which poses a threat to the entire world-any U.S. action must be well-considered and well-executed in coordination with our allies and the Iraqi government and military, which we helped train and arm. Iraq should know that it needs a unity government now or its future will be bleak. Some of the biggest GOP cheerleaders for the disastrous war in Iraq are now joining the blame-America-first crowd rather than working with our Commander-in-Chief to confront this crisis.”

Sen. Lindsey Graham, R-S.C., a long-time supporter of the Iraq War and opponent of President Obama’s pullout, told reporters Thursday after a closed Senate Armed Services Committee briefing that “the next 9/11 is in the making.” Graham said Syria is becoming the next Afghanistan, the former haven of Osama bin Laden, and that the Iraqi government will be overrun without immediate U.S. air power to aid the Iraq army.

Graham said Obama is committing the same mistake that former President George W. Bush made in thinking that once former Iraqi dictator Saddam Hussein was ousted by the U.S. invasion in 2002, the U.S. could rest easy. Graham said he made that mistake himself but “learned the hard way.”

Graham urged Obama to rethink the U.S. withdrawal from Afghanistan, predicting that a similar scenario will play out there, but much faster, when U.S. forces leave.
