No it isn`t. There is only one fact of life. You are born and then you die. There is no such thing as "one" human nature. As if war were a practical survival scheme or as if there's only one human nature.
actually there is...you sound just like your dumb ass boy friend saying there is no such thing as family values...
look up archetypes, you really think that certain books are popular with millions of ppl is coincidental? you think that its a coincident that movie plots from different cultures are similar?
its human nature to protect yourself and seek to further your genes...guess what happens when you have limited resources?
there are many different aspects of human nature and fighting is part of it...to deny that is ignorant
you think that a primate being dominant in order to further their place and acquire mates isnt in their nature?
there most certainly are things that are part of human nature and when youre denied these things you do what you have to in order to obtain them such as fighting or in other words WAR...not everything can be talked out
no matter how bad you want it obamas utopia isnt the way the world works
