NOT "quite" in anything like the American usage.

It will be interesting to consider how a mature politician might respond to the rudeness of someone holding high political office in another country. Eamonn de Valera's response to Churchill's characteristic growling after the end of the 1939-45 War, at least in Europe, has been described as "magisterial". The Long Fellow was An Taoiseach at the time, and would be "Chief" for far longer than Sir Winston.
