Legal Basis for Defending the Ballistic Missile Capability of the Islamic Republic of Iran in the International Community

History has always been complete with the advent of new technologies that have brought about so much change in the world. The ballistic missile opens a window on countries' military and political talents and adds to their scope of international power, and authority. The weapons characteristics of ballistic missiles such as range, accuracy and speed in carrying heavy warheads, as well as its non-weapons use in the space industry and satellite launch, have made it superior to other similar rocket. The sensitivity of the international powers over the missile issue is due to the features of this technology in increasing the defense and space capabilities of countries. For this reason, in the absence of the international enforcement rule, they have resorted to arbitrary political and monopolistic decisions. What is considered in this study is the legal requirements for the defense and protection of the missile issue of the Islamic Republic of Iran in the global arena. The findings of the study indicated that the legitimate and peaceful missile activities of the country over the years show the realization of Iran's inherent right in the international system that respects and recognizes the right to missile defense is one of the obligations of the international community against the Islamic Republic of Iran.
