Before I answer, I would just like to say that this thread has been a truly fascinating read.
savagewind, you seem to be trying to say that the natural arrangement of the universe is somehow more rational and productive than human thought and behavior. As has been pointed out, you are comparing apples to oranges. At quantum and molecular levels, things are arranged according to probability, which is mathematical. Human thoughts and actions are not like that, they rely on complex symbolic structures like language which are always adapting to changing conditions, like what we might consider "smart" at the moment.
It seems very strange to me to try to use a word like "smart" to compare these, because I don't understand how strands of protein can be "smart". If they malfunction, causing disease, does that make them dumb? If they cause a beneficial mutation which better adapts an animal to its world, are they smart? I just don't get how you'd apply the term.
I also don't understand your assertion that world peace would be the human-behavior equivalent of the harmony you see in nature. First, where is the harmony in nature? The fuel in your car is a result of natural disasters which wiped out life on a grand, cataclysmic scale. Secondly, how do you know that a perpetual state of war is not the natural way for humans to be?
