Yeah, but we don’t just need technological solutions that can crank out the requisite energy, we need technological solutions that aren’t going to facilitate nuclear proliferation even more than has already occurred. The United States right now is in an insane position vis a vis Pakistan because even though Pakistan shelters the US’s enemies and is effectively a passive-aggressively hostile power, it would be worse for the US (and the world) if the current Pakistani state just collapsed. It’s a nuclear power, after all. What happens if, in the chaos, ISIS affiliates get their hands on Pakistani nukes? Or, I dunno, the Taliban? Or they disappear onto the international market and two years later the Sinaloa cartel proudly announces it’s the world’s latest nuclear power? That’s the calculus with nuclear proliferation.

This is such a drastic risk the US can’t bring itself to do anything about the people who sheltered Bin Laden and the Taliban during the Afghanistan War because that’s a lesser evil than running the risk of losing control of the nukes. Nuclear proliferation is a big deal.
