War is inevitable, hence the importance of developing its opposite through education, that is, with ethical values. The conviction that education is one of the paths that makes peace possible must be embodied in a set of provisions that regulate it in a chair that promotes a culture of peace and coexistence with respect. It is the lesson to be learned, peace as an end in itself and education as a means, whose just defense cannot be war, because it would not be coherent to seek peace through the atrocities of war. In education for a culture of peace, human nature must intervene to manage the opportunity to defend the right to life; from there would derive the conviction that “peace is a right and a duty of obligatory fulfillment”.
