If you are old enough you must be remembering this incident. I am having clear cut memory of this particular incident where we lost 10+ jawans to BD in an armed clash. I even remembering a picture printed on front pages of many news paper too, in which BD uniformed guys carrying a dead Indian BSF jawan by tying his wrist and ankles to a pole & hanging him down, just like how some farmers carrying dead animals.
And, there was a talk surfaces long back on Pakistan gifting its old sub to Bangladesh Navy, when our navy chief asked about this his reaction was "IN need to patrol bay of Bengal too". Dont ask me to provide link for IN admirals's reaction, i cannot. But i can provid this.
In a strategic decision that India is trying to comprehend, Pak has agreed to gift two old submarines to Bangladesh.

So dont expect BD to be our side kick, any thing can happen. No serious power will be happy to have a strong military in neighborhood, & china too doesnt want this scenario and they will do nasty things to sabotage their only military powerhouse in its neighborhood, India. They can do to BD what they have done with Srilanka by giving development aid.
After all we all know forefathers of present day BD population choose not stick with indian federal republic in 1947. I want
BD to choose any fighter other than Rafale any day, anything can happen between us in future after they improved their economy & is growing with tremendous speed, may be we will continue existing friendship or it may turn upside down.
