Controlling both the horizontal and vertical spread of nuclear weapons has been a matter of international concern since nuclear weapons began to be developed in the early 20th century. There are three main types of weapons of mass destruction: chemical, biological and nuclear. While all three types can proliferate and pose a serious threat to international security, the focus is on nuclear weapons due to their enormous destructive capacity. In today's modern international system, concern centers on the spread of nuclear weapons to international terrorist organizations and unpredictable rogue states. If actors like these were to acquire nuclear weapons, the damage they could potentially cause to the world would be detrimental. As a result, many efforts have been made by countries that already possess nuclear capabilities to reduce and eliminate nuclear weapons elsewhere. Treaties such as the Non-Proliferation Treaty, Strategic Arms Limitation Treaties I and II, and the Strategic Arms Reduction Treaty have been some of the major building blocks of the arms control and disarmament regime, particularly with regards to proliferation nuclear. This regime was initially established by the major world powers in an attempt to maintain the status quo and have only 5 nuclear-armed countries. This exclusionary attitude can still be seen in the actions of the “nuclear club” of countries that already possess nuclear weapons. This nuclear club, which currently includes the United States, Russia, China, the United Kingdom, France, India, Pakistan and Israel, is constantly trying to address the so-called “N+1” problem. The “N” represents the number of states that currently possess nuclear weapons. Non-nuclear weapon states agree to abide by negative security guarantees because they realize that the power and influence that can be gained by possessing nuclear weapons is not worth the decrease in international security that comes from nuclear proliferation. This proposal is particularly effective at preventing horizontal proliferation, which is the primary concern of contemporary and more imminent arms control issues, while tactics such as arms limitations are more effective at preventing vertical proliferation, which was more of a concern at the time. beginning of the arms war. control regime. I believe that an international legally binding instrument prohibiting both the use and threat of use of nuclear weapons against non-nuclear countries should be adopted in order to eradicate any fear of vulnerability on the part of non-nuclear countries.
