I help vacuous neo-Nazi to change ways (5)
I believe the answer is:
india
'i' is the definition.
(India is I in the NATO phonetic alphabet)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for india that I've seen before include "Queen Victoria considered it the Jewel in the Crown" , "land in the East" , ""Bharat", locally" , "where to ring for help?" , "vast country" .)
