Is Iran already a nuclear Power country?? No, but if Joe Biden or any Democratic president comes in the future then definitely it will become. Currently, with many credible sources, it is well known that Iran is already near to making and testing its first nuclear bomb with an 80% proliferation level, and it's very easy to go from 80% to 100% as per scientific capability but Iran is not doing it as its afraid of the sanctions it will face from UN and USA. But if in the 2024 election Joe Biden again comes into power then it's very likely that it will conduct its first nuclear test as Democrats are not as harsh on Iran as Republicans. So, we can say that Iran is waiting for the right movement only.
