Sarah Palin shot back at President Obama today on the issue of nuclear non-proliferation, suggesting Obama didn't have the experience he had criticized Palin for lacking.

The former Alaska governor had criticized the president for adopting a policy of not using nuclear weapons against non-nuclear nations.

Obama dismissed that criticism in an interview with Good Morning America today.

"I really have no response," Obama said. "Because last I checked, Sarah Palin's not much of an expert on nuclear issues."

Palin fired back this afternoon in a speech before the Southern Republican Leadership Conference, suggesting Obama didn't have much experience with nuclear policy.

Palin mocked "all of the vast nuclear experience [Obama] acquired as a community organizer, as a part time senator and a full time candidate."

She also swiped at the Obama administration for disrespecting Afghan President Hamid Karzai.

"They treated the Afghan President Hamid Karzai poorly and acted surprised when he responded in kind," she said.
