Raja raja chola and griffin thanks for understanding my point , it is simple fact that 5 different generations of centrifuge technology in 10'years cannot be possible ( not impossible but you would need industrial knowledge of centrifuge similar to u.s.a. ) if one sees india efforts of 80 -90 s infact back then indian scientist had doubt that pakistan had enriched uranium using centrifuge technique.
Friends , don't need to be personal , espionage is a open fact USSR received complete bomb design from Fuchs and they developed an improved version - 22 kt , it does not mean USSR could not have made the A bomb .
in that manner india could have easily mastered gas centrifuge tech by now , but in espionage it help india go up by 10-15 years.
China has also copied w88 warhead design from China , but it does not mean way back in 1996 chinese economy was weak that they could never make w88 type warhead , it is that such spy work accelerates the nuclear weapons programs and is good for intimidation , Inshort there is nothing wrong if India received a working P4 design which allowed them to test first p4 batches at BARC ( as indicated by BARC in its speech of 2008 , by 2008 the P4 centrifuge were being installed at rattehalli to replace old CNOR designs ) and then proceed to carbon fibre design in which india also tasted success , the old indian design had minor errors , like extra 5mm rotor width etc.
The only thing that is worrying for Pakistanis is the Urs tinner computer contained details of 2 more Pakistani warhead they were new designs ( one was the 1990 design of chic 4 which is known in intelligence circles ) source - fallout CIA secret war with nuclear proliferation and the others seems to be 20-25 kt design or 30-35 kt design (1998 test was this bomb) . ( U.S.A. has copies of entire Urs tinner data and according to them the chic 4 is an excellent design which even if made compact and will definitely work every time in any situation and even a 5 kt bomb can be made and even the design could be stretched max to 25 kt bomb , CIA say they are correct in there analysis as they have the best atomic weapon scientist , they even made a copy of the bomb and threatened not to pursue Abomb to pak foreign minister ( please see the a q khan colum in pak leading paper I remember it title unsung heroes , pak forum members please correct my source , this article was published one month ago ) . In Libya U.s.a. Again got this warhead design papers.
Ok , now regarding technology acquired from China , I am thinking of putting a new thread on that subject as it is going to be real fiery , but the FACT IS jiu shenje ( head of CHINA Nuclear ( like PAEC Head ), in 1980-1970 period ) and Chinese Priemer that time approved the nuclear exchange with Pakistan ( A Q Khan letter to Simon Henderson , many indian newspaper also reported in front page China gave 50 kg enrich uranium , 1967 chick 4 bomb design , 15 ton UF6 , and please see the book deception pakistan United States and nuclear weapons - RAW chief saxsena received deathbed letter of Zulfiquar Ali Bhutto ( by accident the letter was smuggled and landed at an indian origin owner printing press in London ) where he said 1976 pact the most crucial of his life and he will be remembered for that - pack that China will helped liver A bomb to pakistan )
