Democratic strategist James Carville on Thursday joked that it might be best for Republican presidential candidate Mitt Romney if he didn't say anything during his overseas tour.

CNN host Erin Burnett noted that Romney refused to talk about his foreign policy views to CNN, but allowed the Israeli newspaper Haaretz to interview him about the subject.

"I haven't seen Haaretz's interview but I suspect why can't he talk to CNN about foreign policy and he can talk to Haaretz about foreign policy? It doesn't make any kind of sense to me," Carville said.

Romney’s six-day overseas tour has been plagued with troubles. On Thursday, Romney walked back disparaging comments he made about London’s readiness to host the Olympics and accidentally disclosed that he had a secret meeting with Britain's spy chief. The Republican presidential candidate has also had to deal with the fallout from his advisor’s racially charged comments.

"You know what, based on his performance in Great Britain, it might be good that he's shutting up because they're using the 'P' word right now to describe his performance," Carville continued. "That would be 'Palin.' I mean he's gone over there. He's insulted the British preparation for the Olympics."

"Then he goes to the spy service and says that he had a meeting and they -- you know they don't -- they barely acknowledge that they even have a spy service. I mean completely clueless as to what their traditions are. So maybe it's better that he don't say anything. It might be better for him and his campaign if he just kept his mouth shut between now and November."
