Strategic intelligence was a term developed by the early pioneers of “classical intelligence theory” in the United States who combined their academic perspectives with active involvement in the development of the American intelligence community. The term entered the lexicon of intelligence studies in the United States while in Britain, the pioneering academic studies of intelligence made only fleeting reference to them.
