The Left bringing down the house??

As we all know that the Left parties have always opposed anything to do with the United States and they justify this as saying that it is against their ideology.they even oppose the opening of U.S market chains in Calcutta.personally i believe in 'live and let live'.but i think that the Left parties should wake up to the reality that communism as an ideology is no longer viable in this ever changing world and that they should keep up with the times.
It is the age of capitalism world over and that the sun has truly set on Communism as an Ideology and even as a way of life.take China for example,the Chinese government have imposed the Communism way of life on its people but this is done by brute force and not by free choice!capitalism is the way of life now.so it would be better for all of us in India is the left parties would change and change for the better and soon at that!today,the left have given the government of India an ultimatum of sorts-postpone the U.S-India deal or they will topple the government.had the same nuclear deal been proposed by say the Russians or the Chinese,they would have whole heartedly supported it.the Left parties need to 'live and let live' and not oppose anyone just because their ideology demands it!
