Ok, now I am not talking about his other achievements but only his act of telling and upholding truth at all the fora of the world and especially to the people of Pakistan.
Dear brother Muhammad, now don't say, talking is nothing when I will try to draw your attention to Sura Al-Asr where Allah ordains on each of us to advise each other to truth and advise each other to patience and we are in loss if we don't do it.
Advising each other on truth is one of the main and major conditions to save ourselves from loss while only having belief and doing good deeds alone is not enough.
I see many righteous people around like me who think to be a Muslim means only to have belief to the maximum and if you are to be come good Muslim then add good deeds to your faith but they never stand for the truth and are found saying it is none of our business but people like IK are not intimidated to say the truth whatever the forum they get to stand on and he did it throughout his career also at the place you have pointed out UNO and continuing doing so from the Jail of a present day's Yazeed, Hafiz Asim Munir.
This is what the prophets were asked to do and this is what this Ummah of the prophet has been advised to do, talk, communicate, and pass on the message of truth.
Hussain (AI) did the same thing in Karbala and he laid the sacrifices for upholding the truth no one did before and no one may do till The Day comes.
Here is a translation of the Sura for your immediate reference.
By time,
Indeed, mankind is in loss,
Except for those who have believed and done righteous deeds and advised each other to truth and advised each other to patience.
