World - A big home

How about Pakistan and Bangladesh getting united with India and thereafter, what if Bhutan, Nepal and Srilanka wants to join?
Wait, I am not dreaming but contemplating about this for a long time.
One thing is clear that with Globalisation, the economic boundaries of the countries are no longer there and an integration at higher level is on cards. A good example is the European Union. With its 27 members, it has proved to be a success. Further SCO and ASEAN are the two prominent economic blocks in the east and Gulf Cooperation Council (GCC) in the west asia. In the present globalized world countries are being forced to look for the markets outside to realize a higer growth in shortest possible time. It is clear that the economic factors have lead to the formation of certain economic blocks through out the world. These same blocks are further getting integrated culturally with the free movement of goods and services.
Another kind of integration that is occuring is of millitary alliance. NATO is a good example of it. Although these kind of alliances are because of the fear of attack from a rouge country and the strength required to retaliate in such situation, they are also helping to consolidate the integration of nations.
But there are groups which spoils the party. These are like Taliban, Hamas in Palestine, Hezbollah in Lebanon etc. Finally I feel we are moving towards a big consolidation based on the continent or on the lines of strategic partnerships or economic dependence or fear of an attack by a rouge nation.
Whatever be the reason for integration, the thought of our subcontinent as a single country is exciting. Organisations like BIMSTEC and SAARC are already working in this direction but a more cocerted approach is needed to become our day dream to be real.
