Iranian President Hassan Rouhani told North Korea's foreign minister that the United States cannot be trusted, Tehran's state media said, as the United States seeks a deal to rein in the North's nuclear and missile programs.
Iran is a warning to North Korea--not to try to swindle America with a bad deal. If it seems too good to be true, as the Iran deal was for Iran, don't even bother signing. Because it will be a short-term win only, and we will walk away.
And I assume any deal with North Korea over their nukes includes revealing research and supply links to Iran regarding nukes and missiles.
So Iran does not want North Korea to come to an agreement with America. Yet North Korea may fear Iran will, despite their hostile talk, cut a deal first to avoid sanctions.
The prisoner's dilemma sucks for them, Iran may find out.
