I think you're right and that didn't occur to me during the episode. I was puzzled as to why M'Benga seemed so authentic in his conversation with Pike stating "I didn't start the fight." Didn't gibe given that they're longtime friends. But that makes sense.So i think its obvious that when MBenga refers to 'I didn't start the fight' he is referring to the war, and that the fight started a long time ago but never ended until this point.
