The heart-rending plight of Dr. Abdul Qadeer Khan, as telecast by the Waqt channel and narrated by his brothers, has made all of us in ashamed of ourselves. The maltreatment of the saviour of Pakistan, who saved us from Indian hegemony, is condemnable. His 'Ehsan' (favour) on Pakistan, of giving us nuclear parity with our erstwhile foe, was repaid by his solitary confinement in true tradition of Muslim Ummah. Hazrat Ali (RA) had said that one should beware of the evil of the person upon whom one has bestowed an 'Ehsan'. This is so true of us in Pakistan where even Mr Zardari and the Prime Minister Yousuf Raza Gillani do not feel competent to release Dr. Qadeer due to fear of Mr. Bush and Musharraf. We should remember that the mighty war machine of Japan proved futile against the nuclear threat from U.S.A. It needed only two nuclear bombs to bring Japan to its knees in World War II. The same fate could have been ours if we did not have nuclear power vis--vis India. It is time that we showed our gratitude to this great hero of Pakistan. -DR M.
