Agreed, the results were very hazy and disputed. Bottom line, Pakistan shouldn’t have any enriched Plutonium unless they bought it somewhere. With all the HEU they should have by now, why not test a uranium based bomb?
The findings of the specialists at Los Alamos who claimed to have detected traces of plutonium during the Pakistan tests were disputed by other agencies who claimed that the air samples had been ‘contaminated’. So there’s little evidence to conclusively prove or disprove either claim (The Pakistanis claim they tested HEU based weapons).
