Globalism overwhelming island (4)
I believe the answer is:
bali
'island' is the definition.
(Indonesian island)
'globalism overwhelming' is the wordplay.
'overwhelming' indicates the answer is hidden within the clue (the clues covers up or 'overwhelms' the answer).
'BALI' can be found hidden inside 'globalism'.
(Other definitions for bali that I've seen before include "mountainous island" , "Indonesian holiday destination" , "Indonesian island, capital Denpasar" , "Javanese island" , "Bail out of the island" .)
