Well said. and now to respond to your previous arguements:
first of all, war is needed in society because it is a waste of resources. a population is so productive, some governments need to direct that produce into war because the citizens need to be prodictive sothat they are easier to manage and sothat they dont try different things that could potentially be destructive to the establishment. also, finding a common ennemy is a great way to unite a populace and is a great place fir everyday families to direct blame (for economic problems, etc.) i guess i was wrong to say war is necessary in a society, but it is useful and also, as i explained earlier, very difficult to avoid. the reson i got off track into my second paragraph was just because of my ADD
and a lack of communication is, essentially, the cause of all conflict. people with different opinions are simply people with access to different media, different upbringing and/or different information. i beleive that at a very fundamental level, there is no such thing as opinions, only correct and incorrect. if you want me to argue that point, just ask and i'll be happy to. and isolation is pretty much the best way for someone to deceive others into beleiveing their "opinions". there will always be some who are isolated, be it mentally, physically, phycologically or any other form. it may not be as easy as you think to keep the entire population of the world so well informed as you claimed. even if you posess the means, there are many who are unwilling to learn.
"through co-operation and technology, we could tame the globe" you say. well you will not find co-operation. people need the nationalism and the pride and the competition. even if you did manage to create a world wide government, each country would still compete and fight and rebel and expand and they would be so different, the net effect would be pretty much the same as having individual governments. we need the diversity that comes from seperated countries. we cannot afford to stamp out certain perspectives and ways of life. if human technology and knowledge is to increase, then decreasing the diversity with which to acheive it will not acheive it.
next your going to tell me that you would preserve each culture and no ideas would be stamped out. well you cant do that and keep everybody united perfectly informed at the same time. a message to some people may seem very different to others.
Hesitate over that one
