State in USA: it’s wild (7)
I believe the answer is:
tunisia
'state' is the definition.
(I know that Tunisia is or was a African country)
'in usa it's wild' is the wordplay.
'wild' indicates an anagram.
'in'+'usa'+'it'='inusait'
'inusait' anagrammed gives 'TUNISIA'.
(Other definitions for tunisia that I've seen before include "Country in North Africa" , "Country between Algeria/Libya" , "African republic on the Mediterranean coast" , "Land" , "North African republic" .)
