It's now Zimbabwe (8)
I believe the answer is:
rhodesia
'it's now zimbabwe' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for rhodesia that I've seen before include "Previous name of Zimbabwe" , "Salisbury was its capital" , "former state" , "Former name for today's Zambia and Zimbabwe combined" , "country that declared independence" .)
