CHARLOTTE, N.C. -- Democrats sought to push foreign policy, one of President Barack Obama's strengths, to the forefront of the White House campaign Sunday, casting Republican Mitt Romney as out of touch with the nation's international priorities and unprepared to manage them.
Vice-President Joe Biden, campaigning in York, Pennsylvania, painted Romney as a warmonger who opposes ending the conflicts in Iraq and Afghanistan and is looking to start new military action in Iran and Syria. He made the claim without offering any proof.
"He said it was a mistake to end the war in Iraq and bring all of our warriors home. He said it was a mistake to set an end date for our warriors in Afghanistan and bring them home," Biden said. "He implies by the speech that he's ready to go to war in Syria and Iran. "
The campaign did not immediately respond to a request for details on Biden's claim. Biden did not use similar language on Syria and Iran at a later stop in Green Bay, Wisconsin.
Romney's campaign dismissed Biden's criticism. "It's no wonder that a politician who has been wrong about every major foreign policy question of the last 30 years is wrong on every count about Gov. Romney's strategy to restore America's leadership role in the world," spokeswoman Amanda Hennenberg said.
Biden's remarks were a rare mention of foreign policy in a campaign that has been dominated by the economy. Polls show Obama leading Romney on who voters see as stronger on foreign policy issues, an uncommon advantage for Democrats on the issue.
Romney has said he would consider military action in Syria if the war-torn country's chemical weapons were at risk of falling into the wrong hands. Obama, who has opposed military action in Syria, has called it a "red line" for the U.S. if Syrian President Bashar Assad's regime were to use chemical or biological weapons.
And like Obama, Romney has said the U.S. must keep all options on the table, including a military strike, when dealing with Iran. But Romney has suggested that Obama has been too soft on Iran and -- without offering specifics -- said he would prevent Iran from obtaining a nuclear weapon.
Romney raised eyebrows when he failed to mention the Afghan war during his prime-time acceptance speech at the Republican Party's national convention last week.
Romney senior adviser Eric Fehrnstrom on Sunday defended the omission during an interview on CNN's "State of the Union." Ferhnstrom said Romney had already addressed the issue the day before in a speech to the American Legion veterans group.
"But Gov. Romney's convention speech was an opportunity for him to introduce himself to millions of voters who were seeing him for the first time," he said. "In that speech, he accomplished what he set (out) to do, which is to talk about his better vision for America, with more jobs and increasing wages. He talked about the failures of the Obama presidency over the last four years."
Obama's campaign plans to play up that foreign policy strength during the Democratic National Convention, set to open Tuesday in Charlotte, North Carolina. Massachusetts Sen. John Kerry, a possible second-term secretary of state under Obama, will highlight the president's foreign policy record Thursday night before Obama formally accepts the Democratic nomination on Thursday.
Obama himself trumpeted his foreign policy credentials Saturday during a rally in Urbandale, Iowa.
"I said we'd take out bin Laden and we did," said Obama, referencing the raid he ordered that led to the death of the al-Qaida leader.
Former New Mexico Gov. Bill Richardson, an Obama supporter, previewed some of Kerry's likely message on Sunday.
"The president has gotten us out of Iraq. We're getting out of Afghanistan," Richardson said on CBS' "Face the Nation." "We've got free trade agreements in Latin America we have a president that brilliantly dealt with the situation in Libya, with the Arab Spring."
Thousands of delegates and volunteers were arriving in Charlotte during the Labor Day weekend ahead of the Democratic convention.
About 600 people marched Sunday through Charlotte's central business district to protest corporate greed in a demonstration that was lively but smaller than organizers had touted. The marchers carried signs and banners, banged drums and chanted on a sunny afternoon as part of the March on Wall Street South. Their numbers were a fraction of the 5,000 that organizers expected for what was likely to be the week's biggest protest.
Romney spent Sunday at his New Hampshire vacation home. He and his wife, Ann, attended church services Sunday morning at the chapel of the Church of Jesus Christ of Latter-Day Saints in Wolfeboro, New Hampshire.
Campaign officials said Romney would spend much of the Democrats' convention week preparing for the presidential debates.
Obama campaigned Sunday in Boulder, Colorado, on the middle leg of a trip to battleground states in the lead-up to his convention.
