Lord Krishna's arguments are consistent with peace because he is asserting the idea that if individuals submit themselves to his will, one can rest assured that they are doing the right thing. This is where Lord Krishna's argument of working not for the fruits of labor, but rather for one's own sense of duty, is relevant For Lord Krishna, the fundamental argument is that war, malevolence and violations of the highest degree are perpetrated because one is attached to the "fruits of one's labor." When individuals become attached to these fruits, evil in the world becomes apparent. Bhakthi Yoga is the path through these forces. The way to defeat the Duryodhanas in the world is to relinquish the fruits of one's labor and submit entirely to Lord Krishna. The literal translation of Duryodhana's name is "difficult to fight with," reflecting how challenging it is to relinquish these fruits of one's labors. Yet, in doing so, one finds peace. In surrendering the fruits of one's labor and submitting to the will of Bhakthi Yoga in the way of Lord Krishna, peace can be achieved. It is for this reason that the great charioteer guides Arjuna. Consider his words to Arjuna in this regard: "Giving up all vexations and paths, do thou take refuge unto Me. I will save you from all dangers." It is here in which peace can be found. Lord Krishna's arguments are consistent with peace because he stresses that when individuals surrender attachment to the fruits of one's labor, however difficult this is, peace is evident. Individuals no longer see to take what isn't theirs for there is no possession. Through this sense of devotion to Lord Krishna, peace becomes evident.
The relinquishment of the fruits of one's labor is designed for human beings to be relieved of conditions that are the opposite of peace. One need only examine the Kauravas attachment to wealth, property, and lust for power as an example of this. Lord Krishna knows very well that this appetite cannot be satiated. It is rooted in obsession with "the now," and is attached to that which is unreal. Nothing can curb it if one is so attached to it. Through this, war, destruction, and malevolence are evident. Only through surrendering such attachment can peace be realized. Lord Krishna understands this and, like all good charioteers, guides Arjuna to this realization in the divine song.
