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.

Uh... Cars are fuel tanks on wheels...

Yes. All cars and vans in the UK drive a total of 320 billion miles a year. My own electric car tells me this would require 80 billion kWh. 1kWp produces 1000 kWh a year, so you need 80 million kWp or 80 TWh a year.
My house will easily provide 8kWp, meaning you'd need 10 million houses. There's 30 million homes, and that's before you factor in non-domestic buildings.
A single shooting estate in the uk could produce 20TWh a year with solar alone. Throw in wind and that would petty much double.
