With estimates of annual coal, gas, and oil demand in 13,229 global population centres and 8,165 global power stations, we use a minimum-cost flow method to estimate global asset-level energy flows.
If you want to protect your country, here are your options:
1) Invest in nuclear power and nukes (source of Uranium may be a concern). See North Korea vs Iran.
2) Solar on every structure, every vehicle is an EV. This will be the most resilient, distributed grid that can never be disrupted. Node level failures (hail on roof breaks solar) can be easily overcome. EVs are batteries on wheels! They can go charge and come back. Some on this forum may be familiar with Cattle vs Pet, Redundancy, Resiliency, Virtualization (--> Virtual Power Plants), etc -- same concepts, but applied to power generation which is designed as a monolithic circuit switched network. The idea of energy as packets, which can be Store-and-Forward (using batteries) will change everything we know about energy.

Both countries invested in nukes (it is claimed). Only Iran didn't get there in time, before the US stepped in to stop them (it is claimed). So unless the US lets you, it's probably a bad idea to invest in nukes, no? Or is your point that the US's nuke story was a lie, and that Iran actually should have invested in nukes?
> Solar on every structure, every vehicle is an EV
Have you done any calculations as to whether this would actually work? My gut feeling is that even if you put solar panels on literally every structure, you'd be far off from managing to power every vehicle. See if I get around to calculating later, but I at least advise you to do so yourself before making this argument.
> EVs are batteries on wheels! They can go charge and come back
Uh... Cars are fuel tanks on wheels...

EVs go 2-5 miles per kWh.
So, the charge rate is 20-500 miles per hour when the sun is out.
Assume one extra EV per house, round robin. New EVs are $10-60K, depending on county. The solar is, say, $30K.
So, $60-210K per house for ten years of energy independence for a two car ICE house. ICE cars wear out faster than EVs. You can figure gas, grid and inflated maintenance on the ICE route yourself, but the math works.
Of course, used EVs more than halve my estimates,

Gonna need a citation on that, given that the average EV battery lifetime is 10-20 years.
