If Barack Obama needed a way out of tango dancing in Argentina, he should have recalled Nancy Reagan’s maxim and “just said no,” Charles Krauthammer suggested tonight.

In a lighter moment on Friday’s Special Report, Krauthammer joked that the embarrassing episode highlights Obama’s inability to be assertive.

 “It does explain why we gave away everything in the Iranian nuclear negotiations,” Krauthammer said. “The guy can’t stand up to a tango dancer, how is he going to stand up to the mullahs?”
