Invasion of East Pakistan or Bangladesh was the biggest blunder modern India made in its entire history. Now what we have are two enemy nations on each side of the border and two enemies to negotiate with instead of one before. The politicians were very short sighted at that time. The problem of the refugees from Bangladesh has not been resolved, the pretext to the war. The population of Bangladesh will double in the next two decades and India is going to be the only country to absorb the multitudes whether people like it or not. In the old scenario, West Pakistan would have had the legal and moral obligation to do so. The 1971 war has become a political as well as military defeat for India.
