What exactly do Russia, Iran, and NK have to offer the world other than certain natural resources that you can get from elsewhere, and low grade military gear?
""
Firstly, Russia, Iran and NK don't "have to" offer the world anything because they don't owe the world.
Secondly, there some technological sectors in Russia that don't exist anywhere in the world. Or for some, there're only 2-3 countries that have alternatives. This is how much undeveloped and non-innovative Russia is:
* space exploration; engines and tech for spaceships; everything related to space;
* atomic space; atomic power plants
* different types of engines, toubines
* KAMAZ the truck - always wins Paris - Dakar rally
* metallurgy, mechanical engineering
* alternative to SWIFT - СПФС
* alternative to Visa/Master Card - Мир
* most innovative banks - Tinkoff
* alternative to Google - Yandex
* alternative to Youtube - RuTube
* some stuff in the medicine (I'd need to do a search)
* programmers and hackers -- one of the best in the world
* it's own civil airplane - Sukhoi SuperJet
* hyper-sonic missles (a few ones for which there're no alternatives at all and can't be intercepted) - Сармат/Satan, Avangard...
* GLONASS
* tank "Armata" - new generation; no alternatives in the world
* airplane Ту-160М2
* nuclear-powered icebreakers
* nuclear-powered submarines (biggest in the world; no alternatives in the world to some of them)
* cutting-edge figter jets of new generations (1 or a few...) -- which cost 1/10 of those in US yet are on par with them
* AK-47 - has been the best in the world for ... 50 years or so
* Pushkin, Dostoevsky, Lermontov, Tolstoy, Stalin ....
and the like
Forgot:
* VK.com (alternative to Facebook; with free pirated music, by the way)
* Telegram
* Aurus Motors - luxury cars
* Baikal - microprocessors (getting started)
* And of course - Vodka
