Trump thought the Iran nuclear deal was the worst possible even though Iran gave IAEA inspectors unlimited access to any location in Iran. Some nuclear facilities even have 24x7 surveillance by the IAEA. In this deal with North Korea there's just a promise that NK will denuclearize and nothing more. But the Iran deal was a bust and this is a success according to Trump? The North Koreans must have been ecstatic about Trump's promises, the South Koreans must have been aghast.
