Generation Gap

In my political science class, my classmates were talking about many clashes of civilizations in their household, in the world, and many more. Many people's parents don't totally agree on their son or daughters beliefs because they were brought up differently. My sister's husband grandfather sincerely hates my beliefs on the Vietnam war. I believe that it was totally unnecessary and that the United states were wasting their time in Vietnam trying to train the Vietnam soldiers so that United States soldiers could return home, but that sincerely didn't work. My grandfather-in-law argues me down to the ground every time he sees me. He really hates my opinion on the whole situation because he thinks I'm a young punk and don't know what is the basis of the United States history of war. My point is that the generation gap is such a problem facing among the same civilizations and different civilizations. In a stretch of time, many things can be changed. China is,what i would say, expanding. They are not losing their culture. They are expanding and opening up to new things. Many people generations before me would disagree, but it's my opinion and my view upon things as i see it in today's world.
