During an "Early Show" interview Wednesday, Arizona Sen. John McCain continued to hammer home that point, saying that "if we had done what President Obama wanted, we would have failed in Iraq."
"It was President Bush who made the decision over the vociferous option of … then-Sen. Obama, to do the surge," McCain told "Early Show" co-anchor Harry Smith.
McCain's comments echoed by the top Republicans in Congress, Rep. John Boehner and Sen. Mitch McConnell.
During his address, Mr. Obama said the U.S. had "met its responsibilities" in Iraq and it was "time to turn the page" on what is the second-longest war in American history and refocus efforts on restoring the country's shaky economy.
"The United States has paid a huge price to put the future of Iraq in the hands of its people," he said. "We have sent our young men and women to make enormous sacrifices in Iraq, and spent vast resources abroad at a time of tight budgets at home."
Mr. Obama also addressed the ongoing war in Afghanistan, reiterating plans to draw down U.S. troop levels in the middle of next year "because open-ended war serves neither our interests nor the Afghan people's."
Mr. Obama also repeated that a final decision on force levels would be made in light of conditions on the ground, but McCain, long a critic of any notion of military timetables, again criticized president on that point.
"The thing that disturbed me the most is this continued repetition that we are leaving at a date certain. You don't win conflicts when you tell the enemy you're leaving," he said, adding that the July 31, 2011 goal of beginning a troop withdrawal was "purely a political decision."
