Just a thought…by keeping certain nations free of nuclear energy, one can more-or-less assure their relegation to obscurity when their oil runs out. Of course, they wouldn’t be ignorant of that possibility.
Have you ever played Risk with someone who lacked self control? That’s how I imagine an oil-rich nation run by people like Ahminadab might react when approaching the end of its oil. Of course, that’s not an excuse to invade, but it is reason to keep an eye out and to be prepared.
