Tanzanian port makes bold sadly to back America (3,2,6)
I believe the answer is:
dar es salaam
'tanzanian port' is the definition.
(I've seen this before)
'makes bold sadly to back america' is the wordplay.
'makes bold' becomes 'dares' ('dare' can be a synonym of 'make bold').
'sadly' becomes 'alas' (I've seen this before).
'to back' says the letters should be written backwards.
'america' becomes 'am'.
'alas' back-to-front is 'sala'.
'dares'+'sala'+'am'='DAR ES SALAAM'
(Other definitions for dar es salaam that I've seen before include "Port on Zanzibar" , "The largest city in Tanzania" , "capital once" , "foreign port" , "Tanzanian city" .)
