Big Picture

Of course there isn't a list of countries that are in the same situation as Iran but there are some countries that have similar issues. Take Japan. For example, they rely heavily on imports of fossil fuels to get the energy they need. Japan used to depend on their nuclear reactors but since the incident in 2011 they have shut them down for safety reasons. Areas with nuclear reactors say they do not mind starting up the reactors once again.

North Korea is a very self sufficient country based on energy. What they share with Iran is a nuclear program. North Korea began their program in the 1950's, originally for peaceful purposes to help their own country. It eventually turned into a nuclear weapons program that led to the 2006 and 2009 nuclear tests. In 2009 it was estimated that they had up to ten functional warheads and in 2013 they pledged to have more nuclear tests. Currently they have no operational power-generating nuclear reactor but the efforts to develop a nuclear sector continue. As you can see that other countries that experience similar issues cannot do much about it other than to just continue their research.
