Achieving peace and security, and a life full of tranquility under the shadow of these two important pillars, have been among the first demands of humanity from the beginning of history until now, and various actions have been taken in different eras to achieve this noble goal. Achieving peace is always faced with various challenges, and one of its fundamental challenges is the different meanings and concepts in different periods. In today’s world, peace is often seen as the observance of principles such as sovereignty, equality of rights, respect for the sovereignty and representatives of countries, respect for the territorial integrity of countries, non-interference in internal affairs, and resolution of conflicts through peaceful means.
