The Obama campaign is marking the one-year anniversary of the successful mission to kill Osama bin Laden with a new web video hailing President Obama's decisiveness and questioning whether Mitt Romney would have done the same.

The spot features former President Bill Clinton, who validates Obama's leadership as the "decider in chief."

It also resurfaces a statement by Romney from the 2007 primary when he said, "It's not worth moving heaven and earth, spending billions of dollars just trying to catch one person."

An on-screen graphic raises the question: Which path would Mitt Romney have taken?  The suggestion is that under a President Romney, bin Laden would still be alive.

"He had to decide," Clinton says of Obama. "And that's what you hire a president to do. You hire the president to make the calls when no one else can do it."

The video continues a line of attack against Romney initiated by Vice President Joe Biden during a campaign speech Thursday in New York City on foreign policy.

Biden said Obama's record could be summed up in a bumper-sticker slogan: "Osama bin Laden is dead, and General Motors is alive."

He said later, "You have to ask yourself… if Gov. Romney were president, would he have used the same slogan in reverse?"

Romney campaign spokeswoman Andrea Saul praised the military's successful mission to target bin Laden but said it's "sad" that Obama is campaigning on it.

"It's now sad to see the Obama campaign seek to use an event that unified our country to once again divide us, in order to try to distract voters' attention from  the failures of his administration," Saul said in a statement.
