In an echo of his usual campaign speech, Obama noted that the war in Iraq is over and troops are on track to leave Afghanistan in 2014.
"Al-Qaeda's leadership has been devastated, and Osama bin Laden will never threaten us again," Obama said at the Pentagon. "Our country is safer and our people are resilient."
Romney, in Reno, Nev., to address a meeting of the National Guard, indirectly but clearly drew distinctions with Obama by spelling out his own national security goals. "I wish I could say the world is less dangerous now," he said.
After declaring that the day was not the proper moment to address differences with the president, Romney took issue with threatened cuts in defense and the handling of disability claims and called for more assertive international leadership.
"This century must be an American century," Romney said. "It is now our duty to steer it onto the path of freedom, peace and prosperity. America must lead the free world, and the free world must lead the entire world."
He alluded to his criticism of Obama over threatened cuts in military spending that would kick in if Congress and the president don't find agreement on major federal deficit reductions. While acknowledging that the war in Iraq is over and the United States is on a path to exit Afghanistan, Romney warned: "The return of our troops cannot and must not be used as an excuse to hollow out our military through devastating defense budget cuts."
Obama has insisted on a deficit deal that includes both spending cuts and increases in tax increases. Romney has blamed Obama for negotiating a deal that would require steep Pentagon cuts if a broad deficit agreement failed to materialize. But in an interview on NBC's Meet the Press, Romney said he also disagreed with Republicans who voted for that same deal. Among those was Romney's running mate, Rep. Paul Ryan of Wisconsin.
For Romney, the appearance before the National Guard also provided an opportunity to address men and women who have served in Iraq and Afghanistan. Romney has been criticized for not mentioning Afghanistan in his speech to the Republican National Convention. While Romney said Tuesday that the U.S. goal should be to transfer security to Afghan forces in 2014 - the same timeline as Obama's - he cautioned, "We should evaluate conditions on the ground and solicit the best advice of our military commanders."
