Because nuclear weapons are generally considered one of the most important of state secrets, all nations with nuclear weapons have strict restrictions against the giving of information relating to nuclear weapon design, stockpiles, delivery systems, and deployment.
Karena senjata nuklir umumnya dianggap sebagai rahasia negara paling penting, semua bangsa yang memiliki senjata nuklir memiliki aturan ketat terhadap pemberian informasi mengenai desain senjata nuklir, stok, sistem pengiriman, dan pemasangan.
