The most delicious moment of last night’s debate was when GOP presidential nominee Mitt Romney told President Obama, “Attacking me is not an agenda.”

This came after the president listed a series of disagreements he had with Romney’s own foreign policy theories. Romney continued, “Attacking me is not talking about how we’re going to deal with the challenges in the Middle East.”

Romney then addressed the president’s remarks one-by-one. Obama unsuccessfully attempted to interrupt as Romney tackled US-Russian relations.

“Russia is a geo-political foe,” he began. “Russia does continue to battle us time and time again in the U.N. I have clear eyes on this. I’m not going to wear rose-colored glasses when it comes to Russia or Mr. Putin.”

The smack-down concluded with reference to a statement the president made to Russian Prime Minister Dmitry Medvedev when he thought he was off mic. “I’m certainly not going to say to him, ‘I’ll give you more flexibility after the election.’ After the election, he’ll get more backbone.”

Twitterdom went nuts. GOP strategist Karl Rove tweeted:

Romney – attacking me is not agenda. Mitt laying strategic perspective. Obama delivering prepared zingers. #debates

Conservative pundit S.E. Cupp, along with many others, simply savored the moment by repeating the zinger — “Attacking me is not an agenda.”

To that I can only add, and “Osama bin Laden is dead” is not a foreign  policy.
