Nordic countries have had nuclear power plants for half a century.
If they don't have a sufficient secret stock pile of nuclear weapons already, then they have been utter and total fools.
If they don't have secret nuclear weapons in orbit, they have been severely irresponsible.
Let's hope the plans of their leaders is not to send all young men as infantry to the meat grinder to die for a country which hates them, like they are doing in the Ukraine war. But who knows? Life is full of surprises.
Typically the point of nuclear deterrence is to brag about your capabilities, not keep them secret.
