Any nation that has a nuclear reactor running on 3% enriched Uranium has a lot of spent fuel rods filled with Plutonium. The Plutonium just needs to be extracted. When that happens, Krypton gas is released and our spy planes can detect it.
When South Africa gave up its nuke program, it was noted that Israel and Taiwan were probably in partnership with South Africa for the rogue south Pacific test that we saw on our satellites.
Even Sweden had a nuke program at one point. https:// en.wikipedia.org/wiki/Swedish_nuclear_weapons_program
Japan has nukes that can fit on their satellite launch vehicles and are only "a screwdriver away" from being ready to go.
Most experts think that Pakistan's nuke effort was funded by Saudi Arabia and that Pak has "warehoused" some number of nukes for SA to come and get in case Israel or Iran get hot.
Remember: if you have a nuke reactor, you are making Plutonium and it only takes a small leap to extract it – compared to separating U-235 from U-238 in centrifuges.
Open your eyes.
