ONE of Britain's leading nuclear experts, expressing surprise at the speed with which Pakistan carried out its nuclear tests says "Pakistan has had to depend on overseas assistance, and they would look to China in this respect." John Large, nuclear scientist and an independent advisor to the British Parliament on nuclear issues, told 바카라 that "even if Pakistan had a nuclear weapons arsenal, they were not primed up to detonate." In the first stage, he says, a test needs the digging of a hole about two metres in diameter and 400 to 600 metres deep. A chamber has to be built at the bottom connected by cable and a gamut of sophisticated instruments. That Pakistan had such a facility ready is indication that they were prepared to test. But beyond that, testing five nuclear devices needs preparation that would take more than two weeks.
