Enter creed revision as hindrance (10)
I believe the answer is:
deterrence
'hindrance' is the definition.
(I know that deterrence is a type of hindrance)
'enter creed revision' is the wordplay.
'revision' indicates anagramming the letters.
'enter'+'creed'='entercreed'
'entercreed' with letters rearranged gives 'DETERRENCE'.
'as' is the link.
(Other definitions for deterrence that I've seen before include "What nuclear weapons provide" , "What discourages" , "Discouragement" , "The use of fear to dissuade" , "Role of nuclear weapons" .)
