@toiletpaper Meanwhile Wikipedia and movies tell you everything you'd need to know to build your own nuke.

The hard part isn't the design of it - the hard part is obtaining the materials, and of course building such a large and heavy thing in the first place, as you need a quite strong (and radially symmetric) explosion to suddenly push it together to set off the chain reaction.

As such, _every_ country is "one year apart from building a nuke". The knowledge is there, so once one can obtain the material, it's just a matter of time.

Oddly though, this fact is only ever brought up for _some_ nations...
