I dont think USA is retarded. Iran was negotiate to detract from nuclear energy for decades. Trump is just the only president that decided to do something real about it. You can ask AI for past negotiations from Europe and the US toward Iran and their nuclear projects. You can also search for Iran's threats to Israel and the US. And finally you can look for direct links of funding of Iran to Hessbola, and other terrorist organizations. Even the Train bombing in Spain and the bombings in London were tied to these islamic terrorist groups all tied with the Iranian regime. https://www.britannica.com/event/Madrid-train-bombings-of-2004
