International head after conflict showing caution (8)
I believe the answer is:
wariness
'caution' is the definition.
(wariness is a kind of caution)
'international head after conflict' is the wordplay.
'international' becomes 'i' (abbreviation eg in IMF).
'head' becomes 'ness' (ness is a headland**).
'after' means one lot of letters go next to another.
'conflict' becomes 'war' (war is a kind of conflict).
'i'+'ness'='iness'
'iness' after 'war' is 'WARINESS'.
'showing' is the link.
(Other definitions for wariness that I've seen before include "State of caution" , "Circumspection" , "Caution, watchfulnes" .)
