Country wasn't prepared to stop snake (8)
I believe the answer is:
botswana
'country' is the definition.
(Botswana is an example)
'wasn't prepared to stop snake' is the wordplay.
'prepared' indicates an anagram.
'to stop' indicates putting letters inside.
'snake' becomes 'boa' (boa is a kind of snake**).
'wasnt' anagrammed gives 'tswan'.
'tswan' placed within 'boa' is 'BOTSWANA'.
(Other definitions for botswana that I've seen before include "Country east of Namibia, north of South Africa" , "Central African state" , "Landlocked southern African country, capital Gaborone" , "Africa country, until 1966 called Bechuanaland" , "Boa wasn't found in the African state" .)
