Yimaphi amazwe ngaphandle kwamazwe ayisihlanu aziwayo anezikhali zenuzi athole, noma okucatshangwa ukuthi athole, izikhali zenuzi?
Context:Ukwanda kwezikhali zenuzi ukusabalala kwezikhali zenuzi, izinto eziqhekekayo, kanye nobuchwepheshe bezikhali zenuzi nokusetshenziswa kolwazi ezizweni ezingaziwa njenge "Nuclear Weapon States" yiSivumelwano Sokungasasazeki Kwezikhali Zenuzi, esaziwa ngokuthi yiSivumelwano Sokungasasazeki Kwezikhali Zenuzi noma i-NPT. Ukwanda kwezikhali kuye kwaphikiswa izizwe eziningi ezinezikhali zenuzi noma ezingenazo, njengoba ohulumeni besaba ukuthi amazwe amaningi anezikhali zenuzi azokhulisa amathuba empi yenuzi (kuze kufike futhi kubandakanye lokho okubizwa nge-countervalue okubhekiswe kubantu abavamile ngezikhali zenuzi), ukuphazamisa ubudlelwano bamazwe noma besifunda, noma ukwephula ubukhosi bezwe bezizwe.  Ngaphandle kwamazwe amahlanu aziwayo anezikhali zenuzi, kunamazwe amane aye athola izikhali zenuzi, noma kucatshangwa ukuthi athola izikhali zenuzi: i - India, iPakistan, iNorth Korea, ne - Israel. Ayikho kulezi ezine eyingxenye ye-NPT, nakuba iNorth Korea yajoyina i-NPT ngo-1985, yabe isishiya ngo-2003 futhi yenza ukuhlolwa kwayo kokuqala kwe-nuclear ngo-2006. Okunye ukugxekwa kwe-NPT ukuthi lesi sivumelwano sibandlulula ngomqondo wokuthi yilawo mazwe kuphela ahlola izikhali zenuzi ngaphambi kuka-1968 abonwa njengamazwe anezikhali zenuzi kuyilapho wonke amanye amazwe ephathwa njengamazwe angenazo izikhali zenuzi angahlanganyela esivumelwaneni kuphela uma enqaba izikhali zenuzi.  Ucwaningo lokuthuthukiswa kwezikhali zenuzi lwaqalwa phakathi neMpi Yezwe II yi-United States (ebambisene ne-United Kingdom neCanada), iJalimane, iJapane ne-USSR. I - United States yayiyizwe lokuqala futhi iyona yodwa eyasebenzisa izikhali zenuzi empini, lapho isebenzisa amabhomu amabili eJapane ngo - August 1945. Ngemva kokuzinikela ukuze kuqedwe impi, iJalimane neJapane zayeka ukuhileleka kunoma yiluphi ucwaningo lwezikhali zenuzi. Ngo - August 1949, i - USSR yahlola isikhali senuzi, yaba izwe lesibili ukuqhuma ibhomu lenuzi. I-United Kingdom yaqala ukuhlola isikhali senuzi ngo-October 1952. IFrance yaqala ukuhlola isikhali senuzi ngo-1960. I-People's Republic of China yaqhuma isikhali samandla enuzi ngo-1964. I - India yaqhuba ukuhlolwa kwayo kokuqala kwe - nuclear ngo - 1974, okwabangela ukuba iPakistan ithuthukise uhlelo lwayo lwe - nuclear futhi, lapho i - India iqhuba uchungechunge lwesibili lokuhlolwa kwe - nuclear ngo - 1998, iPakistan yalandela ngochungechunge lokuhlolwa kwayo. Ngo-2006, iNorth Korea yaqhuba ukuhlolwa kwayo kokuqala kwezikhali zenuzi.
I-India, iPakistan, iNorth Korea, ne-Israel.
