> These risks seem vastly overstated for a large fraction of the world. That such events happen occasionally does not mean the entire world needs to be on a war footing all the time. That would be incredibly wasteful. That’s part of the problem. It’s an asymmetric risk/cost issue. The attackers only need to get it right once, you need to defend your installation constantly. Security for nuclear power stations already increase the upkeep cost considerably.
