Explain the role of the U.S. in the emerging global community?

Global community implies a world in which barriers and
differences between people based on nationalities are diminishing. These barriers have
not been lowered because of  planned attempts of any big and powerful countries to
create a global community. The global community has emerged as a result of evolving
technology and the resultant increase in global trade and
interaction.

Global community has emerged because people
exposed to a wide range of concepts, and cultures have accepted and adopted what they
liked best, irrespective of the the source of such practices. This has enabled people to
choose what is best suited or liked by them irrespective of the constraints of their own
community and culture. This has enriched lives of individuals, and at the same time
developed better understanding among people of different
countries.

What the U.S. or any other country can do to
promote global community is to not to encourage any actions that tend to isolate their
people from rest of the world by creating a false sense of their superiority over
others. Development of global community is because of the free choice given to people by
the technology. The best way to speed up this process is to not to create new barriers
between people.
