The US government deliberately publicly posted documents showing how to make a nuclear device. So, if Iran does come up with the bomb, it’s most likely to be based on the information contained in those documents. In the 1980s the US and other countries sold Saddam the means to build the WMDs it later used to justify invading Iraq, and it looks like the same scenario is in place for Iran now. It really is starting to look like the USA is the biggest threat to world peace and security.
