Small republic Romanians destroyed (3,6)
I believe the answer is:
san marino
'small republic' is the definition.
(I've seen this before)
'romanians destroyed' is the wordplay.
'destroyed' indicates anagramming the letters.
'romanians' with letters rearranged gives 'SAN MARINO'.
(Other definitions for san marino that I've seen before include "place with no coast" , "Small independent republic in NE Italy" , "No marinas in this small republic in NE Italy" , "nation" , "Smallest European republic (24 sq miles)" .)
