There is good reasons for Bangladeshis to be irked in having India in the neighbourhood.
There is a justifiable vibrancy in Bangladesh since they have acquired a new identity after 1971 and there is a feeling of justifiable pride. They want to translate this pride into action and be counted. This is natural and it should be appreciated.
It is also natural for anyone to compare with others. This is more so accentuated since the history of India and Bangladesh was a common one before 1947 and all were equal in opportunity.
However, owing to a late entry into the independent status i.e. 1971, they find it annoying that while Indians are no way superior to them when compared with the situation pre 1947, yet they find themselves unable to keep pace with India. It is natural this leads to frustrations.
Hence, as is also usual, one tends to seek scapegoats for their own infirmities and so they find one.
Had Nepal been Bangladesh's neighbour they would have no problem of recounting their pluses and minuses. Likewise, even though Myanmar is a much larger country than Bangladesh flush with minerals, oil and timber, they do not have any issues with them since Myanmar has not really progressed to grip Bangaldeshis with a negative equation with Myanmar.
