Sir: The Aam Aadmi Party (AAP), by its recent views on national issues, has shown that it is too young to take over the reins of the nation. Our country is varied in culture, in political ideologies, has been riddled with terrorist and secessionist activities, has regional parties indulging in vote-bank politics and has cross-cultural migrations across the country. A referendum cannot, therefore, be a solution to our problems. Minuscule countries elsewhere, whose size is much smaller than Mumbai city, can have different types of governments. Our problems are humongous, compounded by some unfriendly neighbours. AAP has a long way to go before it can think about entering the national stream. Let AAP prove its credentials by effectively governing Delhi for five years, by implementing the 17 points that Kejriwal has listed, by initiating action against the alleged corrupt practices of Sheila Dixit, Suresh Kalmadi and others, by ending the water-mafia raj in Delhi, etc. Governing and governance are easier said than done. The way AAP is manoeuvring, Mulayam may prove right in observing that the “bubble of AAP will burst very soon”. HARISCHANDRA PARSHURAM Mumbai
