Re: sindhis not happy with pakistan
Sultan bro! Feeling slighted, disenfranchised is something Bengalis always had. Just see their struggles with Hindu Bengalis over 100 years prior to Pakistan. Bengal was divided and united so many times that they lost count.
Second point! you say Bengalis had "Genuine grievances". Do you know of any grievances that are "Non-genuine", fake, made-up etc? I am sure not.
A grievance is just that! A grievance! If you have one, it would be a genuine one, and I can bet the bottom dollar on it.
However no grievance should ever drive you to commit anti-state terror. Because if you do, the state would come at you with all its might. It doesn't matter if that state is democratic, dictatorial, monarchy, or Khilafat. No state in the world at present or past would allow a section of its populace to rise up against the state.
Coming back to your point, Bengalis took only few months after their "liberation" to have Mega-Grievance against Awami League and especially against Sh. Mujib. And the result of such grievance was most shocking and most terrible.
Sh. Mujib, his sons, daughters, grandsons, grand daughters, chacha, Nana, phopha, khaloo, khala everyone related to the "founder of BDesh" was murdered nay crushed to pieces by none other than Bengalis.
So there you have it. Bengalis had grievances against the whole world including themselves. No one even god himself could address those "Genuine grievances".
Burqa, prior history of East Pakistan may be tumultuous but that does not change the fact that there were genuine problems which were not timely addressed by the Central govt. based in West Pakistan such as economic development, proper national discourse on the national identity as well as the representation of the Bengalis despite being about half the population of the United Pakistan. All this in addition to the embedded sense of arrogance and racism espoused by us towards the Bengalis. If one delves into the tumultuous history of the regions of Pakistan it would be perhaps quadruply more tumultuous than that of the East.
Second, let me try to make you understand what I mean by by genuine grievance. I mean a reasonable affliction as measured by its popularity among the designated peoples as well as ground realities. If minorities in Pakistan such as Ahmedis, or Christians grieve that they are deprived of certain inalienable rights or that they are persecuted for example, even if someone like you argues that they are harping exaggerated annoying bellyaches, it still would not change the ground realities that their situation or their national confidence is quite shaken because of concrete events and state tolerated bad fortunes. Similarly, in Pakistan if women gripe that they don't have equal status to men or that they don't even have a quarter of oppertunities available to men, someone may dismiss all of this as hogwash and feminazi banter. Still it wont change ground relaities.
You do realize I can goon and on right? Pakistan itself was founded on the basis of disenfranchisement faced by the muslims was it not?
As to your points that State retaliates to terrorism. Terrorism should not be allowed to engender in the first place. Organized terrorism is more often a socio political development than some religious or fringe or deranged phenomenon. And if it does happen, a good leader, a strong and just leader would definitely go after those who carried out the act but at the same time would speed up the process of reconciliation, dialogue and redress. A stupid establishment, an unjust cruel establishment would send their soldiers who would murder, rape, pillage and then shamelessly surrender to a lost cause forever marring the pride of a nation. Now of course like you said, an imprudent leadership may retaliate with full might of the state butchering, bombing people left right, but far from solving anything it results in absolute decay and entropy. If anything, that's what we have and should've learned.
And on your other point on what happened to Mujib afterwards is irrelevant. Pakistan too was created on just grounds, it turned out like this is irrelevant.
