I think that would be like a totalitarian state,so can't support it.
Bangladesh is and always will be a defensive country.If we declare India as hostile,then we will become the aggressors,one which we can not afford!
We import many goods from India,now if we declare them hostile,then I guess you know we will be short on supplies of many goods,including many food items.
To remind you,we are very far from being self-sufficient.So showing such audacity as to declare India an enemy is not the right option at all.
BUT if India attacks BD,which might be possible if BJP comes to power.In that case we have to fight to save our motherland and our army should be prepared to do that.
Moreover,I think India would not do this foolish thing,as it has lot at stake here.India's NE region is very unstable,any chaos near this area could allow ULFA,MULTA and other organisations the initiative which India don't want.
Above all,we are not at a state of war with India.So our status should be CAUTIOUS,not hostile.We should be cautious as we all know India cannot be termed as good neighbours.
