Nyika dzipi kunze kwenyika shanu dzinozivikanwa kuti dzine zvombo zvenyukireya dzakawana, kana kuti dzinofungidzirwa kuti dzakawana, zvombo zvenyukireya?
Context:Kupararira kwenyukireya ndiko kupararira kwezvombo zvenyukireya, zvinhu zvinoputsika, uye zvombo-zvinoshandiswa tekinoroji yenyukireya neruzivo kumarudzi asingazivikanwe se "Nyukireya Weapon States" neChibvumirano cheNon-Proliferation yeNuclear Weapons, inowanzozivikanwa seChibvumirano cheNon-Proliferation kana NPT.

Nyika ina kunze kwenyika shanu dzinozivikanwa kuti dzine zvombo zvenyukireya dzakawana, kana kuti dzinofungidzirwa kuti dzakawana, zvombo zvenyukireya: India, Pakistan, North Korea, uye Israel.

Tsvakurudzo yokugadzirwa kwezvombo zvenyukireya yakatanga kuitwa muHondo Yenyika II neUnited States (pamwe chete neUnited Kingdom neCanada), Germany, Japan, uye USSR.
