It's been 40+ years, why do we care about an apology anymore? Look at where we are today (in spite of having a zillion problems, not to mention a nation born to a massacre/blood bath) and look at where they are. What goes around comes around and Pakistan today is a failed state and will likely continue to be one - just the harsh truth, no offense to anyone.
They had their chances to apologize, but four decades is long enough for us to say we don't care about an apology anymore and that they can continue to hide international terrorists and go bomb and destroy themselves further for all we care.
Screw the IPL, I'm going to the MLC
