I teleport a hostage about to be executed to a capsule in lunar orbit. I then offer you three options: you pay me 1,000,000,000$, and I give him whatever pleasures are possible given the surroundings for a day, and then painlessly kill him; I simply kill him painlessly; I torture him for a day, and then painlessly kill him, and then pay you 1,000,000,000$.
Do you still take the money?
This strikes me as a pretty stark decision, such that I'd have a really hard time treating those who would take the money any different than I'd treat the babyeaters. It's almost exactly the same moral equation.
[...] Often I find that the best way to come up with new results is to find someone who's saying something that seems clearly, manifestly wrong to me, and then try to think of counterarguments. Wrong people provide a fertile source of research ideas.

Indeed: the background probability of a sane leader launching an unprovoked trade war on the rest of the world is near zero. 10% would be unsettling, 30% would be (and was!) alarming.
