Sure, but posessing some of the materials needed for producing such a weapon is indeed illegal due to the Atomic Energy Act of 1954. Here is an article about some tangentially related recent events that mentions it (and explains as well)[0]. Owning a personal nuclear weapon might not be technically illegal. However, producing it and transferring it is illegal. Which, seems to be almost functionally equivalent to being illegal to possess. This is just purely my thoughts on how that hypothetical could play out, but I would be lying if I said I wasn't stupid curious about it myself. 0. https://www.washingtonpost.com/archive/politics/1978/03/19/weapons-grade-uranium-offer-probed-by-fbi/44d65d33-5390-433d-b5b9-b44843a9a80e/ https://www.washingtonpost.com/archive/politics/1978/03/19/w...
