Baghdad's nation (4)
I believe the answer is:
iraq
'baghdad's nation' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for iraq that I've seen before include "Saddam Hussein's country" , "Country containing Basra" , "Middle East republic, capital Baghdad" , "Country to west of Iran" , "Mosul's country" .)
