Pakistanis also celebrated the rise of Taliban in Afghanistan, but now they are accusing the same Taliban of targeting Pakistani citizens under India's influence. Terrorist attacks in Pakistan have significantly increased since Taliban came to power in Afghanistan. They fail to realize that the nature of relations between India and Afghanistan will not change, regardless of who comes to power in either country. same is true for India-Bangladesh relations.That is somewhat true in terms of Assam and parts of W Bengal with high Muslim population but most BD'shis accept the past is the past. It is time to deal with current realities now.
I really urge you to listen when BD political leaders like BNP and even Jamaat speak about BD-India relations. They all say that BD and India should have friendly relations and both should respect each other.
We have a noisy minority in BD that likes to blame India for everything that goes wrong in BD but they do not represent the majority. Yes the majority may think that India can sometimes be over-bearing but that is to be expected as India is by far the largest country in the region.
Nothing is helped by listening to the fringe who just like to find external enemies when most of your problems are due to your own doing. Focus on the many common interests that both BD and India have.
