Pacifist in America jumped off cliff (4)

I believe the answer is:

dove

I believe this clue is a double definition.

'pacifist' is the first definition.
(dove is a kind of pacifist)

'in america jumped off cliff' is the second definition.
(past tense of 'dive' in American English)

(Other definitions for dove that I've seen before include "Pigeon-like bird" , "Small pigeon" , "Cooing bird" , "Bird in the pigeon family" , "Bird; advocate of peace" .)

I've seen this clue in The Independent.
