War is a very complicated subject but you have to understand that war can be neccesary and even vital.
My personal definition of war would be: A conflict between two forces over one thing; a large series of battles or feuds.
You see, there are 3 types of people when it comes to war. Everyone fits into one of these 3 catigories.
Passivist: A person who hates war and doesn't want to have anything to do with it.
Most people would (honestly) say that they fit into this category. They think that all war is wrong and that it is nothing but senseless fighting. What they don't understand is that if someone were to live in a passivist country, than you would never be able to defend yourself from an attacking country. You would never be able to councure land and you could easily be taken over by a surrounding country.
Activist: A person who thinks that War is good for EVERYTHING. An example of a famous activist would be Adolf Hitler. They think that at even the slightest problems or just because of mear hunches that they should go into war. There are also certain indian tribes that followed the activist role such as the Osage indians of Arkansas.
Not many people would like to claim to be activists and they would probebly like to say that America or any other country that is currently in war is activist. The only reason many people think this way is because they're in a war and they don't know why because they'd rather complain that you do reaserch and find out. (please don't flame
)
cercomstantial: This way is usually thought to be most reasonable, but not used often. Many people would like to say that they were in this category, even though they fit into another. Be a cercomstantial in war situations would mean that you would go to war, when you needed to. If you were trying to defend you country or to gain land would be good examples. to be cercomstantial, you would have to take a lot more things into consideration and a lot of thought is necessary. Unfortunitily, many people don't like to go through the thought process and go on the feel of the moment.
One more thing, I believe that America is currently at war because we are trying to protect our country. If anyone thinks otherwise, feel free to tell me.
I hope this answers you question.
