The large house in a plush district of Pakistan's capital, Islamabad, that was once his home is now his prison.
Dr Khan has been confined to house arrest since his
confession in February 2004 that, as the man who had helped deliver the
nuclear bomb to his native Pakistan, he had gone on to transfer nuclear
secrets and technology to an array of countries around the world.
Next to the main building sits a guesthouse in which Dr
Khan used to entertain his friends and contacts, including many of the
Western businessmen who worked closely with him.
Now, the guesthouse is the site of the security detail
that monitors Dr Khan's movements and ensures there is no unauthorised
contact between him and the outside world.

His confession took place somewhere in 2004.
He did the real job of making a bomb 10 or more years before the confession.
Could we write today that 'he had helped
deliver the nuclear bomb to his native Pakistan' and 'he had gone on to
transfer nuclear secrets and technololgy to an array of countries
around the world'?
I have difficulty in understanding the necessity of the past perfect tense here.
I would like to hear from you all.
