Without war in the Pacific (8)
I believe the answer is:
peaceful
'pacific' is the definition.
(similar in meaning)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for peaceful that I've seen before include "Amicable" , "Serene" , "Calm and undisturbed by strife" , "Quiet" , "Placid, not belligerent" .)
