I would be interested to learn how Iran was to test their nukes.
What you find is lots of info on missile testing, and almost none on nuke explosions. My gut feeling is that Iran always had some relationship with North Korea, and their tests were cooperative in nature. Course, if North Korea is the source....and they end up with a peace treaty with the US/South Korea...that’s the end of the nuke testing phase, and Iran would have to start it up themselves. Just one single explosion would then prove Israel and Trump correct.
