Don't think answers re winning world cup as hosts are correct answers.
As a Scot 1966 is etched in my brain when England won the world cup as the host nation.
Win the World Cup as hosts seems the best answer. Yes it was done in 1966 (England) and 1974 (West Germany) but the last time before France done it in 1998 was in 1978 (Argentina), so it fits in witht the question.
Incidentally, it happened in the first two competitions too (Uruguay, 1930 and Italy, 1934).
