No.
MI has one meaning and one meaning only: It is that specialty within the US Army dealing with the analysis (and partly the collection) of data about the enemy, potential enemies, and the environment in which friendly forces might operate. It has nothing to do with James Bond type issues, and only deals with national level issues insofar as they impinge upon national level military/army operations and contingencies. It is purely military, though on infrequent occasions it will deal with civilian agencies.
If you want a realistic idea of what MI does (as opposed to the Hollywood portrayal of it) think about a civilian "Business Intelligence Analyst." Very nearly the same thing but applied in a different milieu.
The NSC is the President's forum whose principle duties involve advising the President on national level security matters. It is almost completely civilian, though the Chairman of the Joint Chiefs of Staff has a seat on it.
I would also add that the NSC is not even considered part of the "intelligence community", although the NSA and NIC are (civilian agencies).
