Fools country about international slaughter (13)
I believe the answer is:
assassination
'slaughter' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Maybe there's a link between them I don't understand?
'fools country about international' is the wordplay.
I cannot really understand how this works, but
'country' could be 'nation' (synonyms) and 'nation' is present in the answer.
'about' could be 'a' (abbreviation in Chambers) and 'a' is found within the answer.
'international' could be 'i' (abbreviation eg in IMF) and 'i' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for assassination that I've seen before include "(Eg, political) murder" , "Murder of a prominent person" , "Merciful, lenient" , "Ordered killing" , "Politically-inspired murder" .)
