Controlling the horizontal and vertical proliferation of nuclear weapons has always been a matter of international concern since the development of nuclear weapons began in the early 20th century. There are three main types of weapons of mass destruction: chemical, biological and nuclear. Although 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 focuses on the spread of nuclear weapons to international terrorist organizations and unpredictable rogue states. If such actors 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, the Strategic Arms Limitation Treaties I and II, and the Strategic Arms Reduction Treaty were some of the early building blocks of the arms control and disarmament regime, particularly with regard to concerns nuclear proliferation. This regime was initially established by the major world powers with the aim of maintaining the status quo and having only 5 countries with nuclear weapons. This exclusionary attitude is still visible 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 deal with the so-called "problem". N+1”. The "N" represents the number of states that currently possess nuclear weapons...... middle of paper ...... onal cooperation. States that do not possess nuclear weapons agree to comply with negative security assurances because they realize that the power and influence that can be acquired by possessing nuclear weapons are not worth the reduction in security international situation resulting from nuclear proliferation. This proposal is particularly effective in preventing horizontal proliferation, which is the primary concern of more looming contemporary arms control issues, while tactics such as arms limitation are more effective in preventing vertical proliferation, which was more of a concern. at the start of the arms war. control regime. I believe that a legally binding international instrument should be developed that prohibits both the use and the threat of use of nuclear weapons against non-nuclear countries, in order to eradicate any fear of vulnerability on the part of non-nuclear countries. nuclear..
