We haven't tried? Kiddo, Pakistan is ahead compare to you in Nukes. We tested short range nasr first, you followed us. We tested MIRV capable Ababeel first and you're still in developing MIRV since last 5 years. We tested Babur first. We tested Ra'ad first. We have more nukes than you. Its simple that we didn't failed because we completed our home work properly
Countries failed during testing of Nukes but India is exceptional because almost every nuke of India has failed test 4-5 times before becoming operational
and more you quote, more your idiocy + jealousy coming out.
BTW more you test nukes, more your failures are coming out
