Nuclear Proliferation and International Security Case Studies of Iran and North Korea

The widespread existence of weapons presents a threat, to global security as evidenced by the circumstances involving Iran and North Korea. Both countries pursued nuclear policies, leading to regional and global conflict. Rightly needing peace, Iran’s nuclear energy has faced international skepticism, resulting in sanctions and the Joint Comprehensive Plan of Action to Control its Nuclear Activities (JCPOA) but the effectiveness of "the JCPOA remains controversial", worrying Iran to comply according to the law. In contrast, North Korea's nuclear program is growing more military, with many tests of nuclear weapons and missile launches in defiance of UN resolutions. Despite international attempts, including treaties and penalties, North Korea's nuclear development continues to deteriorate, defying global non-proliferation rules. Global security requires better international collaboration, robust verification methods, and long-term transnational solutions.
