I know your question is retorical, but i think your point holds a dangerous truth: if other countries deserve access to nuclear weapons, the world likely ends up getting more nuclear weapons. Since there hasn’t ever been anything so deterring as nuclear weapons, that might get us closer to world peace. But it might also not.
It sounds sketchy, but the text show she herself asks about it and for me that answer doesn’t come across as manipulative or him trying to profit off of her. It would be more worrying if he’d answer something like ‘o that car? You could let me use it’ or ‘I can sell that for you’. I think it’s wrong to assume all old people are vulnerable confused and sick, and also wrong to assume a sex workers has less moral values because of the way they choose to make a living. I think the way they communicate show that a) she has a sound mind and b) he treats her honestly like a friend and not as a target or victim.
Have you also read she lives in Canada while the claimants live in Australia and waited four years to voice their concerns? That says a lot too I believe.
