I don't know about food independence, you would need to ask Iranian members, I'm just extremely anti-Zionist/American and this is the most important thing going on now.
North Korea has already done the R&D, I don't doubt that getting the necessary schematics and tech from them would be an easy process, if Iran doesn't already have them. If the US is distracted by Iranian nuclear weapons then that would put less pressure on NK. Though Iran and Nk's nuclear/missile program diverged long ago, there are still channels for cooperation and there is evidence of recent TOT going back just a few yrs ago.
