"It was in the south of England. And I sat down and I said, ‘America is back,’ and Mitterrand from Germany, I mean from France, looked at me and said – said, “you know what — why — how long you back for?"

Nothing to see here. He knows what he's saying. Sharp as a tack. Copious Cognitive Abilities.
