OIC was established in 69 Bhutto came to power in 71,he was not among the founders.
In one of his rallies he asked the people if Pakistan should recognise Bangladesh the people said:No,No.
Then he said ok to hell with them.
Then to fool the people he called the OIC meeting in Lahore,invited Sheikh Mujeeb ur Rahman and recognised Bangladesh.
And the fools think he was a hero of muslim world.:lol:
