You are mixing it up!
It is a simple thing that before 1971 Bangladesh was Pakistan and Biharis migrated there after partition means they migrated to 'Pakistan'.
Thanks for the history lesson, I didnt know that
They migrated to Pakistan, but chose Bengal, not West Pakistan, was my point. The could have migrated to West Pakistan, if they wanted to, but decided on Bengal, because they (Biharis) are closer ethnically to Bengalis (as is obvious from any map).
Then they fought with Mukti Bahinis and Indian army to save Pakistan.
I agree, where did I disagree with this? However I do think that Pakistan doesn't need to take these extra Biharis, since it's already taken its quota of Biharis, and given them full citizenship rights, plus no other country in the world gives people citizenship on the basis they fought for their cause. The French didn't for the Morrocans are one example. They took some in though, but not every Morrocan that wants to come in. Pakistan should (and is) following the same model. I think where I differ with you is that these extra Biharis should be exchanged for Bengalis. I see it as very justifiable, since Bangladesh holds them in concentration camps denying them citizenship even though the war is over, so if the Bengalis are deported from Pakistan, Bangladesh will give them full citizenship in Bangladesh, the Biharis can have ful citizenship in Pakistan, that would solve all the problems, and there would be no change in the demographics of Pakistan.
When did Afghanis fight for Pakistan?
Third Battle of Panipat to stop the Maratha advance towards the Indus Valley.
It’s not about people of not present day Pakistan’s origin. The thing is how much we feel for the people who fought for Pakistan and if any one doesn’t care about them this means he never knew the ideology of Pakistan.
Pakistan invested 20 years in Afghan war and what is the result? Think yourself.
The Afghan war was fought by Pakistan for the interests of Pakistan. Stop thinking so unilaterally. Pakistan entered the Afghan-Soviet war for its own interests, not those of the Afghans. The Soviets wanted to advance into Balochistan, plus destroy American bases in Pakistan. Pakistan helped the Afghanis because it was next in line for the Soviets. An Afghani could argue they fought the war to save Afghanistan and Pakistan, a Pakistani could argue they helped Afghanistan gain its independence from the Soviets. Reality is somewhere in the middle, both countries acted in their own interests. Anyway, Pakistan was more of a conduit for American supplies into Afghanistan, rather than expending men for battle (the human toll was mainly on the Afghanis), though it's possible the some Pakistani forces had a role in some battles (like the hilltop one with 9th company). Personally, I feel Afghanistan would have been better off under the Soviets though.
