People worked in NATO (6)

I believe the answer is:

nation

'people' is the definition.

'worked in nato' is the wordplay.
'worked' indicates anagramming the letters.
'in'+'nato'='innato'
'innato' with letters rearranged gives 'NATION'.

(Other definitions for nation that I've seen before include "Race" , "People of a state" , "The Birth of a -, D.W. Griffiths film" , "Country, state" , "Turkey?" .)

I've seen this clue in The Sun.
