Eli5: Why is it so difficult for countries to build nuclear bombs?

1.16K views

I understand the technology is difficult. My question is more about how is it that some countries have achieved a nuclear arsenal and other countries are still trying? You’d imagine if the scientists and engineers of one country could manage it, those of another country would eventually get it too. Seems an odd convenience that the most dangerous weapons on earth are prohibitively difficult to make. So few humans are smart enough to make them that only 9 countries have achieved it?

Many countries can build nuclear weapons, but they don’t.

When you have nuclear weapon, everyone will be more cautious to you, some will stop supporting you finacially and gonna apply a lot of ban to you to punish you for having “mass destroy weapon”

Would you still want to play with neighbor kid if you know he can destroy your entire family whenever he can ?
