An adviser to Republican presidential nominee Mitt Romney says that part of the former Massachusetts governor's debate strategy on Tuesday night will be to ask President Barack Obama to "man up" and "accept his responsibility" for the terrorist attacks in Libya.

"There should be an effort to get transparency from President Obama on what he knew and when he knew it," Romney foreign policy adviser Amb. William Richardson told Fox News host Bill Hemmer on Tuesday. "This was evidence that his so-called success on the war on terror wasn't so successful. Targeted killings alone can not solve this problem."

"This helps provide a choice to the American people between more of the same and strong, optimistic, bold leadership under President Romney."

He continued: "I think Gov. Romney will, quite properly, be asking questions, probing. And trying to ask the president to man up, accept his responsibility and explain to the American people the failure that resulted in four American deaths."

If Richardson's preview of Tuesday night's debate is correct, it could signal part of a broader tactic of subtlety questioning the president's manhood.

During the first debate, Romney had compared the president to his sons when they were "boys" and didn't tell the truth.

Last week, one of Mitt Romney's son even likened Obama's debate performance to "an obstinate child."

"I don't know if you guys saw the debate last week," Josh Romney told a crowd in Van Meter, Iowa. "I take a lot of pride in that, because — I don't know if you noticed, but I was — me and my brothers were responsible for my dad doing so well. We were the ones, as kids, that kept saying the same thing over and over. And we'd say the same lie over and over. And my dad learned then, not to believe it. While we didn't go to any of the formal debate preparation, we did the real hard stuff."

"So as a father, he learned how to debate an obstinate child," the younger Romney added. "We had a lot of fun, we had a lot of fun watching the debate."
