Today, cases such as international terrorism, misuse of civilian aircraft as a weapon with high destructive power, transfer of weapons of mass destruction, piracy and hijacking in the high seas threaten international peace and security. One of the effective tools of governments in this regard is to control and monitor the flow of civil aviation, which is being carried out according to ICAO operational standards and regulations. Inspection and, if necessary, interception of civilian aircraft is one of the early stages of the control and monitoring process. In this article, the interception of civilian aircraft over the high seas is examined based on the principle of territorial sovereignty and the protection of international peace and security. It is not under the jurisdiction of any country (open seas), what is its status and justification, and if it is allowed, under what conditions and principles should it be done? It seems that governments, as members of the international community and in line with taking care of national security in the first place and international peace and security in the second place, have taken measures in the field of exercising territorial sovereignty and fulfilling obligations related to participation in taking care of public order and security, which is necessary The development and progress of the world is done, which includes the interception of offending civilian aircraft, an issue recognized by the rules of international law and supported by the Security Council as the main founder of international peace and security.The current research is applied in terms of its purpose, and in terms of the method of collecting information, it is a library, and the data analysis will be done qualitatively and with the descriptive method and content analysis.

Under the UN Charter, the Security Council is the primarily responsible organ for keeping international peace and security. For this end, it has taken a variety of actions, one of which is the establishment of international criminal courts such as the International Criminal Tribunal for the Former Yugoslavia and International Criminal Tribunal for Rwanda. The purpose of these courts is to punish international criminals to maintain or stabilize peace. In addition, International Criminal Court has been established to combat impunity of great criminals. Overlapping functions of these two, on the one hand, and the dependency of International Criminal Courts on States and the Security Council together with the negligence on the part of the Security Council in its primary responsibility given by the Charter, on the other, underlie the interference of the Security Council in jurisdiction of the mentioned courts and lead to the non-realization of international criminal justice and the perpetuate continuation of justice practice based on discrimination in international criminal law. This article aims to study the relationship between these two important international institutions and has come to this conclusion that in their interrelationship, the priority is given to the promotion of international peace and security over universal criminal justice.

Nowadays in the postmodern era the challenges facing the states and international community requires very different responses from international law system and different roles for the system too. The trend of globalization and rising new trans-national threats against peace and security in international relations have radically transformed the nature، governance and basic objectives of the international law in the recent years. The international problems from border pollution to the terrorist camps and from flow of refugees to the proliferation of weapons are all locally rooted that no international law system could often have the power to deal with them. In the meantime، one of the important and controversial international، regional and national phenomena in the initial decade of 21st century and beginning of third millennium، and one of the basic international problems and challenges and the most dangerous threat to the international peace and security is the issue of terrorism. In the other words، the spread of increasing terrorist actions and operations are the most challenging issues before the world community and international criminal law which are observed as the serious threat against peace and security in international relations. In the age of globalization and with expansion of terrorist threats as a result of postmodern، terrorist have also developed alongside of globalization، yet never caught by the constrains of it. In this regard، no state، region or nation can be invulnerable by terrorist actions. Terrorism from a national threat has gone to international threat and eventually become global. Thus، there is a feeling of concern and fear that with the spread of this phenomenon in the world and their access to the dangerous nuclear، chemical and biological weapons they could rapidly endanger international peace and security. In the light of globalization or from a cosmopolitan perspective، not only international law and idea of peace، but violence also such as the phenomenon of violent terrorism as the outcome of September 11 becomes general and global in nature. The international law has majorly focused on trans-national terrorism as it is against the international peace and security. Thus، at the present، the postmodern concern regarding the international law is all about how to maintain international peace and security and prevent the outbreak of war. Since the states look at issues and mostly problems through the eye of national interests، confronting international terrorism in the course of international law and in persuasion of peace will face serious challenges and obstacles. The international law can merely be successful tackling terrorism while the international law treaties and conventions are implemented in an appropriate environment، and the political and legal conflicts to be resolved at the world community level، and the trans-judicial principle of international law should not only be about peace among states، but also among human kinds and its future. Therefore، a firm international law system with multilateral principles and procedures are required in order to redefine the rules of an emerging global civilization. On the other hand، a serious rethinking at the global level is needed in which all the elements consisting international relations must be reviewed and studied with a series of new definitions and re-conceptualizations. The focus of this research work is that how the legal system of international law can deal with the postmodern terrorism in the era of globalization and create understanding، comparison and adaptation between two legal and political fields in order to provide global peace and security. The author believes that the pluralistic synthesis of global alliance for international peace with the rule of universal international law and multilateral cooperation of international community and combination of new international relations theories could pave the way for a kind of international law system which would be able to confront with unilateral aggressive strategies of the violent post-September 11 to fight terrorism in a systemic and coherent way. Therefore، international law in the era of globalization by relying on the values of peace، development، freedom and democracy could only restore the United Nations and save the world from scourge of global terrorism and its consequent threat emerged of postmodern and work as a safety valve providing the context for peace and security n international relations.

The international community has seen a significant increase in drones in the recent past and their application in the trans-terrestrial area. These technological devices have moved beyond the bounds of peace and have actually entered the realm of war. Depending on their use in the international community, drones are contemplated from three fundamental areas of international public law: international human rights, international law The use of force and international humanitarian law. While the third area is more concerned with this, it is not exaggerated to speak of the impoverishment of specialized Persian literature of international law in the aforementioned dimensions. This article is intended to provide a comprehensive overview of the use of drones. Overall, drones should not be considered as a wicked phenomenon; the fact is that these technological tools, like any other human-made device, can step in the direction of international peace and security. However, the use of drones to date, especially by the US, Canada and the Zionist occupation regime, suggests that these tools are seen as infringing rather than contributing to international peace and security.

The outbreak of the corona virus has shown how weak and vulnerable humans are at the same time as authority. Failure to announce the incident in a timely manner and the lack of preparedness and lack of coordination between governments made it difficult to respond and deal with it quickly. A sharp dispute between China and the United States over the origin of the virus led to its refusal to include it in the Security Council agenda.The main focus of this research is on the global epidemic of coronary heart disease and international peace and security, and seeks to answer the question thatIs the disease a threat to international peace and security? The Council's practice and practice indicate the expansion of its competencies and its extension from military to civilian threats. The council has twice before decided on AIDS and Ebola. Both times saw the situation as a threat to international peace and security. If the Council wishes to use the same logic in describing and attaining the status of the corona, it will, as in the previous two cases, declare it a threat to international peace and security, given the extent of the spread of the disease. But he didn't, and he probably won't. However, the Security Council has taken a passive approach in this regard, and little can be expected to change, at least in the short term.

Following the evolution in the concept of peace and security, UN Security Council has considered climate change as a threat against international peace and security since 2007 in its 5663 meetings. The consequences of the climate change will vary around the world. Some countries may encounter severe storms and floods resulted from melting of polar ice caps while others may face droughts. Increasing earth temperature which is one of the most important consequences of climate change endangers human security and life especially in the developing countries. It also exacerbates social and economic poverty and finally results in international and non-international conflicts. Also, there are some hot places in the world which are likely to be the main victims of these changes but the effects would threaten all nations. This article, explaining national and international consequences of climate change, tends to consider the relationship between these changes and international peace and security in light of different state observations in Security Council’s meetings.

The programs of international peace and security require global arrangement. It is widely accepted that social and economic issues will impact on international peace and security. World Bank efforts to achieve target of helping developing countries and poverty reduction. The high level of poverty in the world is not only morally unacceptable but it increase threat to international security. Peacekeeping has two phases. One of them is before the outbreak of hostilities and attempts to prevent breach of the peace and security. the second is after the outbreak of hostilities in conflict rebuilding efforts and prevent to return to before situation. World Bank confers easy loans with lower interest also offering technical assistance to countries in cooperation with united nation organs .different subjects such as political, economical, environmental topic are affected on international security so achieving this end need international cooperation.

Terrorist crimes are a phenomenon that is the product of various causes, which at the same time is considered the cause of the formation of various situations. From the point of view of the relationship between terrorism and human rights, this phenomenon is the result of the violation of human rights and the lack of conditions for lasting peace. Therefore, it targets respected norms in the world (such as compliance with human rights standards, rule of law, democracy, and international peace and security). In this way, the international community adopted several documents to counter and suppress terrorism by adopting active and reactive policies; But the thing to think about is that unfortunately, the aforementioned documents could not meet the expectations of the international community in the fight against and suppression of terrorism due to the lack of necessary and effective executive guarantees in terms of lack of acceptance and global consensus. Therefore, the violation of the basic and fundamental rights of nations through terror, including gross violations of the right to life, requires that international human rights organizations, while taking serious and preventive measures and effectively dealing with terrorist crimes in all its dimensions, ultimately play a significant role in strengthening international peace and security in the world.

The UN Security Council is primarily in charge of maintaining international peace and security. There has been raised various debates on how the Security Council manage international crises in the world, particularly severe violations of international human rights law. On the one hand, the traditional view to international peace has altered and the Security Council is also in charge of observing the standards of the international human rights. On the other hand, the international community has faced inconsistencies in the use of the veto by its permanent members on the international human rights violations. However, many analysts believe that the Security Council could take timely action to prevent violations of international human rights law. At that time, they fell into the trap of politics and proved insufficient. This article in response to this important issue, indicating that the management of the Security Council has been fair in the case of international human rights violations and in accordance with the fundamental norms of international law. This study also aims to prove fairness shall be the outcome of moderated procedure of Security Council.

The role of legal- international norms in the regulation of relations and how to interact between international law subordinates requires that the strategies (traditional and modern) generating the mentioned norms be studied in order to have a precise understanding of the process of developments in legal- international normalization, and also activism and behavior that guarantees national interests be considered. On the other hand, the process of the development of the norms of international law has taken shape in a kind of controlling confrontation with armed conflict, as the basis of the United Nations’ Charter is to ensure international peace and security, so that prevent the international peace and the order derived from legal norms in legal relations between countries from serious damage and violation. Therefore, the main question of the research is that which one of the theories in the field of international security has the capacity to normalize international law? To answer this question, a descriptive- analytical method was utilized, and the concise conclusion of this study is that the theory of effects- based operations, which is the basis of the common doctrine of the United States of America, is a new strategy of normalization in international law.
