Somehow rest if conflict results (6)

I believe the answer is:

strife

I'm a little stuck... Click here to teach me more about this clue!

'conflict results' is the definition.
'strife' can be an answer for 'conflict' (I've seen this before). I am unsure of the 'results' bit.

'somehow rest if' is the wordplay.
'somehow' is an anagram indicator.
'rest'+'if'='restif'
'restif' with letters rearranged gives 'STRIFE'.

Can you help me to learn more?

(Other definitions for strife that I've seen before include "Conflict, quarrelling" , "Bitter disagreement" , "Discord and friction" , "Warfare" , "Conflict, dispute" .)

I've seen this clue in The Irish Independent.
