Rather, the thing that makes the most sense is for countries to rely exclusively on local power generation, and completely eliminate their reliance on other countries for energy. There is no infrastructure more fundamental than energy, because energy underlies all other infrastructure. Swapping out oil or coal or gas for liquefied hydrogen (or enormous intercontinental power lines) just trades one poor situation for another. Don't rely on any energy that you couldn't immediately switch over to providing yourself, even if it means paying an eye-watering premium.
