Some boycott a warmonger: capital! (6)

I believe the answer is:

ottawa

'capital' is the definition.
(capital of Canada)

'some boycott a warmonger' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'OTTAWA' is hidden within 'boycott a warmonger'.

(Other definitions for ottawa that I've seen before include "capital city" , "somewhere in Canada" , "Canadian city" , "The capital of Canada (6)" , "North American city" .)

I've seen this clue in The Everyman puzzle in The Observer.
