Why are countries having to accept globalization

There are many many ways this question can be perceived. What your answer is, most likely depends on who you are. But when your talking about a country as a whole, thats a little different. I believe the correct answer, is that: Countries around the world are communicating and interacting in order to become a more communicative union. In addition, allied countries are preparing for the possibility of war.
