Doctrine whichever way you look at it (5)

I believe the answer is:

tenet

I believe this clue is a double definition.

'doctrine' is the first definition.
(both can mean a belief or value)

'whichever way you look at it' is the second definition.

(Other definitions for tenet that I've seen before include "A palindromic doctrine or belief" , "Belief or doctrine - a palindrome" , "A palindromic doctrine or creed" , "Dogma or principle" , "Doctrine held to be true" .)

I've seen this clue in The Sun.
