Airmen bombed a country (7)
I believe the answer is:
armenia
'country' is the definition.
(I've seen this before)
'airmen bombed a' is the wordplay.
'bombed' indicates anagramming the letters.
'airmen' with letters rearranged gives 'armeni'.
'armeni'+'a'='ARMENIA'
(Other definitions for armenia that I've seen before include "South-west Asian country, capital Yerevan" , "Landlocked country, an Asian soviet before 1991, capital Yerevan" , "Caucasian republic" , "Landlocked country south of Georgia" , "Republic formerly in the USSR" .)
