A 'national hero' who was removed from his position, convicted and then pardoned, but still removed from any position of authority.
I'd say Pakistan has amply demonstrated that it is willing to rectify security breaches and take measures to remove even 'national heroes' from the scene.
In any case, given AQ Khan's involvement with highly secretive and sensitive Pakistani nuclear, missile and weapons programs, the international community should realize that it is simply not possible to hand over AQ Khan to anyone outside of Pakistani authorities for national security reasons.
The position taken by Pakistan is very rational and justified.
