For France, from what I understand, I would say probably IN*J. They seem as a whole to keep to themselves, unless called upon in a time of need. Like in the Revolutionary War. They are very concerned with the preservation of their culture. The Feeling/Thinking could go both ways. They are rich in art, but art that can be understood by thinking or feeling.
But, then again most of what I am going off of is Jean-Luc Godard films, and they were made in the sixtes, and seventies. So, that's my guess.
I'd go with ESFJ for America and INTP for the Brits, in terms of the spirit of the nation.
