Naturally, a sovereign state requires a national economy. On one hand, you create science and technology, means of communication and transportation, and on the other hand, you want to have self- centered entities with the idea of their own sovereignties. Then the economies clash, the economic interests of sovereign nation- states clash. So, I think the aspiration for peace, the aspirations for love, compassion, as a way of living, the aspiration for liberty, fraternity, and equality was not coordinated with the existence of sovereign nation- states. Either we have to set ourselves free of the theory of nation- states and the idea of sovereignty of the states, or, we have to say that world peace is not possible.
World peace requires a world economy, a global approach to political issues.
We have no time to go into the elaboration of these issues, one is just briefly mentioning them. Secondly, the aggressiveness, the tendency for violence, has been condemned by religion, spirituality. The economic structure we have created after the Industrial Revolution is a structure yielding to exploitation, by the producer of the consumer, maybe not in one's own nation, but where we find markets. The governments of the nation- states became trading companies, and therefore the main concern of the national economy is finding markets for the production that goes on very quickly, very fast, due to technology. Either, the economy will have to take the shape of a global economy, sharing the resources and distributing the products on the basis of equality, freedom, etc., or, there is going to be absence of peace, there is going to be tension, there will be battles fought on the economic level.
