Iran's nuclear program has sparked intense international debate involving major powers such as the U.S., EU, Israel, and regional players. Following historical cooperation with the U.S. before the 1979 revolution, Iran sought assistance from nations like Russia, China, and Pakistan, leading to international skepticism about its nuclear ambitions. Current negotiations face challenges, with the U.S. and allies demanding limits on Iran's nuclear capabilities in exchange for sanctions relief, raising concerns about potential military conflicts in the future.
