Repeats the outcome of treaties (8)
I believe the answer is:
iterates
'repeats' is the definition.
(I know this)
'outcome of treaties' is the wordplay.
'outcome of' is an anagram indicator.
'treaties' with letters rearranged gives 'ITERATES'.
'the' is the link.
(Other definitions for iterates that I've seen before include "Treatise (anag.)" , "Says again" , "Stated repeatedly in treatise" , "States repeatedly" , "Goes over again" .)
