Bomb might be provocative (10)
I believe the answer is:
incendiary
I believe this clue is a double definition.
'bomb' is the first definition.
(I know that incendiary is a type of bomb)
'provocative' is the second definition.
(something incendiary provokes conflict)
'might be' is the link.
(Other definitions for incendiary that I've seen before include "Likely to stir up trouble" , "Fire-raiser" , "getting people excited" , "Arsonist" , "bomb" .)
