That may not be strictly true. Israel and India are allies, and there is considerable belief that one of the nukes that India tested in their tests a few years was in fact Israeli.
This in no way changes the fact that asking Israel to give up their nukes is ridiculous and insulting.
Wasn't there a flash supposedly to the east of South Africa that was attributed to be an Israeli-Afrikaner joint test of a small nuclear device?
Didn't South Africa have nukes and when the ANC, the black communist dictatorship party, took over...they gave it all up?
