Nope, we are not ungrateful. How do you conclude we are? India also had her own agenda of breaking up Pakistan. Again, just because you help[ed us does not give you the right to stop waters flowing into our rivers. Indians must realize any big-brotherly attitude is counterproductive to friendship. Look around, you need our friendship rather than the other way round.
I have met many Bangladeshis in Kuala Lumpur, Singapore, London, Manchester, Los Angeles ... I know what I am saying...
Indian army was reluctant to go into East Pakistan and resisted for long...it was only after political pressure from Indira [after some understanding with Mujib] they went into... they lost some 12,000 to 15,000 men for whom ?? There were 10 million people as refugee in West Bengal then in 1971. India was not in a position to feed them still we we hosted them with dignity... West Bengal then was itself in grave political turmoil with naxal uprising...
India still have very bad relation with Pakistan, even if the theory of dividing Pakistan be considered that does not mean one can be little the sacrifice of the Indian Army for Bangladesh ... Did you think that without Indian Army's support or help you would have achieved independence... Tikka Khan would have made another Baluchistan out of East Bengal ...Pakistan with help of Al Badar etc would have curbed the movement in few months...
Let me tell you we Indians does not want Bangladeshis to rise up in feet and in every drop of hat to tell us how much [read Indians ] have done ... Indians understand one's country's izzat is paramount and is same for Bangladesh too ... at least Bangladeshis stop belittling the Indian Army contribution to war of liberation of Bangladesh...
Regarding sharing river water with Bangladesh, India will never eat into anything that belongs to other countries...because we Indians does not want it... It does not help us in long run ... India does not gain anything by taking water from Bangladesh share ... India has a federal structure and dependent on states governments support... it takes time to get things moving in India with state and central government are at logger heads most the time... there are instances with in India where one state blocking water to another state...
India is soft state... It will only re acts if when it feels its interests are at stake...
Now a incident from my life:
It was in 1978, then I was myself a 12 year old boy, I was growing up in Dhanbad then in the Hindi speaking state of Bihar, I saw a Bangladeshi wandering aimless, he came to our small shop hearing us speaking Bengali, someone promised him to take to Saudi Arabia or some middle eastern country for job and left him in the Dhanbad railway station...This guy was suddenly found in a place where few people understand Bengali... I took him to a local Masjid, they refused to help him inspite knowing the Bangladeshi was a Muslim...
I asked my mother for Rs 50 then in those days it was quite an amount, to help the Bangladeshi to go back to his country / home... Then Rs 50 was big amount for us from lower middle class family ... I took him to the railway station and bid good bye...
It is perfectly fine to fight for one's country's right there is no issue with it anyone but I will caution all Bangladeshis of using the same for political purpose and spread hate ...
