Is it a good idea to negotiate reunification of India Pakistan and Bangladesh?

No. It is not advisable now because of the different systems of governance in India and Pakistan, and the almost breakdown of law and order in the latter country. Our type of democratic set up will not suit Pakistan and hence it is difficult to integrate. May be Bangladesh, but there is no need for that. Already we have lot of border problems with other countries and we need not add one more, Burma. As things are, it is ok. However, nothing stops from a European Union tyoe of understanding, trade and co-operation as it will reduce trade barriers and encourage inter country visits. The currencies though should be left untouched, because of the strength of the Indian economy compared to others.
