Conscious a conflict leads to peace, ultimately (5)
I believe the answer is:
aware
'conscious' is the definition.
('aware' can be similar in meaning to 'conscious')
'a conflict leads to peace ultimately' is the wordplay.
'conflict leads' becomes 'war' (I can't explain this - if you can you should give a lot more credence to this answer).
'ultimately' says to take the final letters.
The final letter of 'peace' is 'e'.
'a'+'war'+'e'='AWARE'
Can you help me to learn more?
(Other definitions for aware that I've seen before include "Acquainted with or mindful of" , "Knowing (of something)" , "Having knowledge of, informed" , "Conscious, knowing about" , "Apprised or informed" .)
