8. The 2015 Joint Comprehensive Plan of Action (Iran Nuclear Deal)
In 2015, Iran and six world powers—the U.S., U.K., France, Russia, China, and Germany—reached the Joint Comprehensive Plan of Action (JCPOA), aiming to limit Iran’s nuclear program in exchange for sanctions relief. The deal was hailed as a diplomatic triumph, with UN Secretary-General Ban Ki-moon calling it a “historic win for diplomacy.” However, it faced domestic controversies, particularly in the U.S., where critics questioned its effectiveness in preventing Iran from developing nuclear weapons.
