1.
I have read of West Bengalis complaining about northern Indian (BIMARU) domination of the federation. The truth is India is dominated by BIMARU (An acronym for people from the "Hindi-belt" e.g. BIhar Madhya Pradesh, Rajasthan and Uttar Pradesh) and southern Indians don't like them and nor do the Marathis.
Marathis are the toughest and most formidable of Indians so Bengalis and Tamils not liking Hindustanis/BIMARUs is one thing but the fiery and proud Marathis not liking them is another thing as people like Jaya Bachan found out.

Pro-BAL intellectuals like Tagore more than West Bengalis and some of the atheists amongst them would ulimately want a united Bengali state of both Hindus and Muslims and feel a great sense of affinity with fellow Bengalis.
Needless to say Jamatis who are another extreme would have nothing but hatred for Hindu West Bengalis.
Mainstream Bangladeshis are in the middle of these two extremes and would definitely feel some affinity with West Bengal Bengalis and Tripura Bengalis.
3. If India did break up I am sure most Bangladeshis would want a strong and prosperous West Bengal and one to act as a buffer between us and our true, historical enemy, "Hindustan" i.e. the Indo-Gangetic race (Ask @
asad71) more about this.
Anyway I am speaking hypothetically in the real world India is a sovereign member of the united nations and speaking of its break up is irresponsible, wild speculation and reduces one's credibility, I ultimately want a positive and beneficial relationship with India.
Anyway speaking of our West Bengali "brothers" let's see some videos of our long lost separated blood "brothers".
