Arab statesmen rejected wrong answer by doctor (6)

'arab statesmen' is the definition.
The definition and answer can be both people as well as being plural nouns.
Maybe you can see an association between them that I don't see?

'rejected wrong answer by doctor' is the wordplay.
'rejected' shows that the letters should be reversed in order.
'wrong' becomes 'sin' (wrong can mean a sin or crime).
'answer' becomes 'a' (abbreviation eg in Q and A).
'by doctor' becomes 'mo' (medical officer. I am not sure about the 'by' bit.).
'sin'+'a'+'mo'='sinamo'
'sinamo' in reverse letter order is 'OMANIS'.
