So the global community on the Internet is a community of people. The first sort wish to establish an economic community, an environment in which trade and business can flourish. These kinds of nations value their standard of living more than their culture. John Lukacs, in his History of the Twentieth Century, say that the twentieth century's defining characteristic is nationalism. I am certain that there are plenty of historians which would like to argue with Lukacs.
Environmental awareness leads to a simplistic form of globalism.
A community of nations may not be a practical possibility. Associations, treaties, agreements, can be made between nations, but true community lies just outside the capacity of nations. Communities like families are bound together by the mutual love of individuals. A nation is a collection of individuals and lacks the collective capacity for feelings such as love. So a group of nations can enter into a relationship, but their ties would not be strengthened by the bounds of love and as such can enter into true community.
