Is having a good relations means giving up autonomy? Why should not Bangladesh have good relations with India or Myanmar or any other country? Having good relations is always beneficial. What makes you say that Bangladesh has taken a decision under Indian influence that most bangladeshis disagree? Who has her government hanged other than those involved in genocide of Bengalis in 1971? Which oil/gas field Bangladesh has given to India that is detrimental to the business interests of Bangladesh?
If you are unhappy with your government, please participate in elections and defeat her. You dont always have to resort to violent means.
