Bees are not prone to warfare. Apart from natural instincts, there's another important reason: their intelligence is quite low.
War, politics, or, in other words, the actions of grabbing money, food, women, or territory are mostly exhibited by higher life forms. Creatures like bees, who are almost brainless, will not engage in a life-or-death struggle unless other beings threaten their survival. Their tiny brains certainly don't entertain thoughts of 'honor,' 'conquest,' or 'progress.'
In fact, except for humans, the vast majority of animals do not attack other animals unless their lives are threatened or for the sake of hunting to survive.
