There is a saying "No one wanted World War I, but war was inevitable". Wars begin without the will of all people, regardless of their education, but because of the problems of the world elite, which leads events in the world. For example, now in order to save the dollar from a catastrophe, next world war may be initiated and we must understand this well. However, what can we do? At best, we can only watch.
I totally agree with u dear Farangis, and teachers must be teach and learn the students how they can live in, and treat with peace. As well as, teaching how they can leave aggressiveness and they hate the destructive wars.
Through the establishment of a package of vocabulary, values, attitudes and customs based on full respect for the principles of sovereignty, fundamental freedoms and human rights, dialogue and cooperation among peoples and cultures, the rejection and use of force culture and coercion of peoples to fight against their will
Teachers are the best models exposed to their students. They can teach their students that solving problems should always be solved through peaceful negotiations. Stability, security and peace should prevail in all countries. War and the use of power to put an end for disputes in the world should not be done through guns and the use of weapons.
Life-skills-based education for violence prevention and peacebuilding promotes the development of knowledge, skills, attitudes, and values required to bring about behavioral change in society, especially students (the future builders of society).
