If you had agreed to handover power to elected leader you wouldn't at least faced the humiliation and we two brotherly country live without any grudges.
You are right it was wrong to not handover power to the elected leader(Mujib). It was also wrong how Bangladeshis(East Pakistanis) were treated and the disproportionate amount of spending between the East and West wings.
However I feel that a lot of that hatred was taken out towards Pakistanis in general instead of directing it towards those responsible. It was the stupid power hungry and greedy politicians. U can see this even today, the disproportionate amount of spending/development in different provinces etc.
(Note: Below is just for the sake of discussion. I'm not trying to belittle all the sacrifices Bangladeshi ppl made)
Yes injustices were done but does that mean that everytime injustices are done public demands secession? If Haseena out of her hunger for power and greed treats one Bangladeshi province wrong should they secede? And if yes then where does it stop? Until every man declares his house a country? Also wouldn't it be unfair to the rest of Bangladeshi ppl who would end up paying for Haseena's actions even though they had no part to play in it?
From the beginning(under British Raj) it was proposed that Bangladesh(probably a different name used), India, and Pakistan be three different entities but the British refused and therefore Bangladesh and Pakistan were lumped together as one. It was obvious that we differed culturally and the only binding thing was religion. Not to mention the geographical separation. Rifts were created and the differences were emphasised between both sides so much so that overtime it became a us vs them kind of thing mainly by the likes of Mir Jafars and Mir Sadiqs among us. It's kind of like what Altaf Hussain does to Mohajir community. In order to get their votes he is always instigating Mohajir this and Mohajir that.
We couldve resolved our differences among ourselves without involving India. There couldve been something like an EU kind of a Union. As in Pak and Bangladesh govern themselves but have same currency and possible joint defence etc. Instead we played right into our enemy's hands.
I hold our politicians and their greed for power and money responsible for causing this mess and I have no grievances towards Bangladeshi ppl but one, which is that they shouldnt have involved India. When two brothers fight, one of them shouldn't turn to the enemy of both of them for assistance.
Even today Bangladesh has a tilt towards India. India has hegemonic ambitions in the region and with its rising power it will try to bend Bangladesh to its will. I hope u guys recognize it sooner than later. Things that happened in the past between us shouldn't keep us from being brothers again.
