Just for creating the bombs, it’s material and proper production factory. Though if any country tried hard enough this is not such a bad hurdle.

The big problem is deciding if it’s worth it on the global political level. Once you start developing nukes you’re gonna find out who your allies and enemies are real quick (via the most powerful countries in the world that already have nukes). Is it worth getting sanctioned and potentially taking a big economic hit? Is there a chance of sabotage from foreign powers? Etc, etc.

It’s easier to just buddy up to the bigger countries.
