Contra gets deal after revolution in Caribbean islands (8)
I believe the answer is:
antilles
'caribbean islands' is the definition.
(I've seen this before)
'contra gets deal after revolution' is the wordplay.
'contra' becomes 'anti' (I've seen this in another clue).
'gets' is a charade indicator (letters next to each other).
'deal' becomes 'sell' (selling is a kind of dealing).
'after revolution' is a reversal indicator (letters revolve back).
'sell' reversed gives 'lles'.
'anti'+'lles'='ANTILLES'
'in' acts as a link.
(Other definitions for antilles that I've seen before include "Caribbean islands" , "Organism's complete genetic material" , "West Indian island group" , "archipelago" .)
