A WORLD WITHOUT BORDERS.

Today, the development of communication, the development of transportation, the development of mass media and international sports like Worldcup and Olympic make ONE of the world. That is, globalization have been in progress rapidly.

However, it doesn't mean that borders of each nations are disappeared. Becoming one world without borders is impossible because of their own culture, language, history and patriotism of each nations.

Of course, there are some advantages in becoming one world without borders.
For example, it can bring peace. There might be no more wars or terrorism. Also, it can bring a balanced development of each countries. A distinction between a developed country and a developing country.

In reality, however, we already are too accustomed to nationalism, racism, our own ideology, ranking each other and distinguishing each other.
Let's take a look Korea as a good example. North and South Korea have other nationality, other ideology and a big difference in economic power. That's why they have been still being separated, even though they have same language and culture.
How about racism between black and white? The discrimination of a race is still going on.
How about Japan and Korea? because of their history, Iraq and U.S.A.? because of terrorism.

In my opinion, in short, although it seems that becoming one world without borders is possible because of progressing globalization successfully, actually it is not possible because of specific factors of each nations like nationality, nationalism and ideology.
