See Orion I understand the offence by indian members , but you must appreciate centrifuge technology is not easy , your rotor has to move so fast that the entire uf6 gas must move from top to bottom , and separate the light 0.3% u235 on the top and the rest is depleted uranium , the piping system is also very complex , the entire piping system is equal to 4 storey building in height , and has do be in micron accuracy.
Unfortunately , it has been speculated by usa intellect other than that there is no proof of a q Khan and india apart from Gotthard Lerch supplying flow meters , pressure gauge valves etc. to india in 1990s , so there could be a link here which was not pursued further , CIA is know to protect allies and friendly countries it even protected Urs tinner by making Switzerland destroy most of the proofs against tinner , it is also known that a q Khan travelled to many countries and employed many people , a q k has himself blamed it on indian people SMB employed and there was not much background check as it was clandestine market , even a U.s.a. Intellect has question india as fourth customers which I find crazy but it means there are people who suspect indias progress , even if CIA or mi6 have info and if it is known to them they will not declare it as india us nuclear deal means nuclear business worth billions of dollars to us and uk treasury which will be in jeopardy if proliferation charges are levied (politics ) . also please note Mossad tried to kill Heinz mebus who was helping pakistan centrifuge program , and raw and Mossad are very closely looped on military and civilian intelligence , they even attempted to bomb kahuta but usa which needed them in afghan war alerted the Pakistanis , and both CIA and Mossad knew AQKhan was supplying Iran and even raw was tracking khan since 1976 , ( one of the pakdef member admitted in replies that he had read a book on raw where it is mentioned they kept watch on pakistan nuclear development from 1960s ( it started from pinstech and kanupp plant )) , after all in 1965 Bhutto had uttered the eating grass comment , which gave clear intentions to india of bhuttos instance. ( Bhutto had tried to get China help for bomb since 1965 then foreign minister , which was confirmed by China in 1976 after india exploded its bomb , I have also mentioned that this was as per bhuttos letter at death ).
