State elected a warmonger (5)
I believe the answer is:
putin
'a warmonger' is the definition.
I know nothing about this answer so I cannot judge whether this works.
'state elected' is the wordplay.
'state' becomes 'put' (I can't explain this - if you can you should believe this answer much more).
'elected' becomes 'in' (in government).
'put'+'in'='PUTIN'
Can you help me to learn more?
(Other definitions for putin that I've seen before include "Introduce" , "powerful leader" , "Russian leader" , "Russian president" .)
