America with new goal; to bomb African country (6)
I believe the answer is:
angola
'african country' is the definition.
(country in Africa)
'america with new goal to bomb' is the wordplay.
'america' becomes 'a' (common abbreviation - e.g. in organisation names).
'with' says to put letters next to each other.
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'to bomb' indicates anagramming the letters (I've seen 'bombed' mean this).
'n'+'goal'='ngoal'
'ngoal' is an anagram of 'ngola'.
'a'+'ngola'='ANGOLA'
(Other definitions for angola that I've seen before include "African state (and Department of Health?)" , "Republic of SW Africa" , "South-west African country, capital Luanda" , "Southwestern African state" , "West African country" .)
