USA was Unhappy On Dr Qadeer Khan's Release

When Dr Abdul Qadeer Khan was about to release from house arrest, in early 2008, the scientist who made Pakistan the 7th Nuclear State in the World, the Bush administration stayed silent, it was disclosed in a cable unveiled by WikiLeaks on US based New York Times newspaper.
Struggling to get Pakistan’s help in the war against Al Qaeda, it could not risk reminding the world of a case Pakistani officials kept saying was closed.
But, privately, it was a different story.Richard A. Boucher, the top State Department official for South Asia, wrote on April 10, 2008, that the embassy in Islamabad should “express Washington’s strong opposition to the release of Dr. Khan and urge the Government of Pakistan to continue holding him under house arrest.” Releasing him, he wrote, would “undermine” what Pakistan had done to fight proliferation.
“The damage done to international security by Dr. Khan and his associates is not a closed book,” he wrote, noting that the United States and others were still dealing with the Khan network’s sale of technology to Iran and North Korea “and possible other states.”
The world, he said, was dealing “with the reality that the uranium enrichment technology and nuclear weapons designs that were sold to Libya are now available to other states and non-state actors.”
Dr. Khan was released 10 months later. Pakistan has barred him from being interviewed by international inspectors or the United States, including about his allegation that others in the Pakistani government knew of his work.
