I don't see a lot of bonhomie for India and Indians from Bangladesh going forward, in trade and of course defence (which is nonexistent more or less, and continue to be so).
You may be a sane person among few Indians, but few Indians see Bangladesh as any different from Kolkata Bongs, and that is where the root of the problem lies.
They also believe BJP/RSS/Shivsena propaganda that Bangladesh is filled with Islamic terrorists. Anyone criticizing Indian narrative or propaganda from Bangladesh becomes an anti-Hindu terrorist. These are not sane narratives, but then India is not a sane country and govt. anymore.
The problem is exacerbated by leaders of lower rung Indian economies surrounding Bangladesh (and that of the center too, like mota Bhai) bad mouthing Bangladeshis (for election strategy), causing irreparable damage to bilateral understanding and relations. It will take decades to heal, if ever.
India has conducted "Faida Uthana" strategy to Bangladesh for the last fifty years, making it a convenient market for its exports, exported expensive tech and managerial labor to Bangladesh to the detriment of our own job-seekers (Thanks to Hasina's lax non-enforcement of illegal Indian status in Bangladesh) and gained tens of Billions in revenue yearly from Bangladeshis spending money in India. All this to the tune of USD50-60 Billion yearly.
Which has not stopped your politicians calling us termites and pole vaulters.
I tell you what - Bangladesh will go forward, with or without India. We don't need India.
India is an unreliable trade partner and your politicians (and Hindutva extremists) are filled with hate for Bangladesh and Bangladeshis.
You bad mouth us on one side of the mouth while offering clichés and platitudes on the other side of the mouth. We in Bangladesh have known for fifty years who you are and what your country represents. This is not for you personally but who you elected and who represents you (Hindutva).
There is no scenario in the future where we can have transit, open borders, use of our assets or markets by India. Those are and will be all on the downswing. We will trade more and more with Muslim economies like Indonesia, Malaysia, Pakistan, Turkey and of course - China. They are far better trade partners and deal with us far more fairly.
Until Hindutva subsides in India, Indian relations with Bangladesh will suffer.
