I was going to get the first post going, but I still need an idea of who has declared their nuclear arsenal, who set one off and who has it developed but hasn't tested it yet out of the four superpowers.

Testing is essentially announcing, as they can detect the signs of a nuclear weapons test.

While it hasn't dropped the bomb that ended the 40s war, Sturvia is currently testing some of their own.
