(CNN) - John McCain's campaign released a new ad Monday that targets year-old comments from Barack Obama about the conflict in Afghanistan, calling them flat out "dishonorable."
The ad comes as the Arizona senator's campaign aggressively steps up its attacks on Obama's readiness to be a commander-in-chief and raises questions about his background with only a month remaining before voters weigh in.
"Who is Barack Obama? He says our troops in Afghanistan are ‘just air-raiding villages and killing civilians,’” the ad's announcer says. "How dishonorable."
The ad refers to an answer Obama gave at an August 2007 town hall meeting with New Hampshire voters, during which the Illinois senator was asked whether he had plans to shift U.S. troops out of Iraq to other terrorist hotspots like Afghanistan.
"We've got to get the job done there and that requires us to have enough troops so that we're not just air-raiding villages and killing civilians, which is causing enormous pressure over there," Obama said of the U.S. mission in Afghanistan.
Those comments were immediately seized by GOP critics. The Republican National Committee sent out a press release shortly after the remarks calling them "offensive," and demanding he apologize. The McCain campaign has also highlighted the comments several times this campaign season. An AP Fact Check later reported Western forces had been killing civilians at a higher rate than insurgents.
"Congressional liberals voted repeatedly to cut off funding to our active troops," the ad also says. "Increasing the risk on their lives. How dangerous. Obama and congressional liberals."
Palin also made similiar comments in an interview with CBS anchor Katie Couric last week and on the campaign trail in Florida Monday morning.
The campaign says the ad will run nationally, though it did not reveal the extent of the buy.
Responding to the ad, the Obama campaign released a statement from retired Admiral John B. Natham.
"Senator Obama has consistently voted to fund our troops in Afghanistan and Iraq and, just as importantly, a proven record of support when they return home," he said in the statement. "That's why independent veterans organizations give Senator Obama higher marks than Senator McCain. Despite consistent distortions of his record, thousands of veterans like myself support Senator Obama because he has the judgment, character and integrity to be a great president. We will need a great president to lead us in these very challenging times."
