Russian fighter in East, respected, went from country (9)
I believe the answer is:
emigrated
'went from country' is the definition.
'russian fighter in east respected' is the wordplay.
'russian fighter' becomes 'mig' (Russian fighter plane manufacturer).
'in' is an insertion indicator.
'east' becomes 'e' ('E' can be a synonym of 'east').
'respected' becomes 'rated'.
'e'+'rated'='erated'
'mig' placed into 'erated' is 'EMIGRATED'.
(Other definitions for emigrated that I've seen before include "moved overseas" , "gone away?" , "Moved abroad" , "Went abroad to live" .)
