1971 - India liberated Bangladesh from the clutches of the evil West Pakistan junta. Whatever may be our reasons for doing it, we definitely respected Bangladesh & allowed it to form a independent country. As with most liberators (US) we could have stayed back & either ruled via proxy or usurped the country. We did not do it. WHAT DID WE GET IN RETURN.
Bangladesh if keen to mend fences with India will have to walk more than half the distance. Show through actions that it means well for India. Give India enough reasons to cherish a relationship.
