Pokhran II didn't happen in 1975 -- which is when NSG was constituted..... but your research on this front is as erratic as all other "facts " you are spreading on this forum... . . ;-)
The deal DOES NOT permit us to test under any condition..... so don't spread that myth on the forum either.... :-)
There is NO UNOFFICIAL BAN ON NUCLEAR TESTING... this is another one of your imaginary "facts" to appear on this forum... ;-)
Finally Jaswant and Vajpayee did NOT assure the world that India will unilaterally and permanently cease to test nuclear devices.... another one of your "facts".... ever heard of a term "voluntary moratorium"?.... there is nothing "unilateral" nor "permanent" about it...
So stop spreading your myths on this forum..... better enter a story telling competition... you might get this year's Bookers prize for fiction...
