Differentiation is a natural matter that exists in human society since the very beginning of mankind and there is no way to ignore it. It is a source of wealth and a reason for human betterment if the principle of coexistence in society is established. Human existence is unworthy of the name "coexistence" if its existence is not for, and with the other.Nevertheless, long time has elapsed since the fall of the former Iraqi political regime and the occupation of Iraq in 2003, the concept of peaceful coexistence among its constituents remains weak, and the legacy of the past continues to cast a shadow over the lives of the Iraqi people, and this people has not been able to find who promote peaceful coexistence and reconstruction of Iraqi society, which is psychologically and materially devastated due to violent conflicts, on the contrary, it has been confined behind flimsy pretexts and blaming the other parties, whether or not they were participating in the political process, and the pursuit of narrow political interests at the expense of the blood of Iraqis.As a result, we have concluded a number of important recommendations and things, as follows:-Working to purify the social environment of the city of Mosul from the diseases of the rupture and narrow factionalism and cases of closure, retreat and autism. -Educational, social, economic and cultural policies must be reformed, which should contribute to the promotion of the option of peaceful coexistence.-There should be constant communication and dialogue among the parties and the basic components of the city of Mosul, with a peaceful dialogue, far away from the use of violent means.- Compromises must be accepted by all parties on minimum demands for the sake of public interest.- The Iraqi government has a duty to dry up the sources of terrorism and to deal seriously with the path of equality and justice and to promote a culture of peaceful coexistence and acceptance of the other. - In general, it can be said that the process of spreading and achieving a culture of peaceful coexistence among the people of Mosul does not only need letters and slogans calling for coexistence and tolerance of the other, condemning the culture of discrimination, hatred, intolerance and rejection of the other, but it also needs to turn those letters and slogans into concrete reality, trying to offer its services to all components of the society without exception.
