To conclude my argument, Politics is not always the realm of human rationality. We humans are inherently an irrational animal. This is a fact most people tends to dismissed. We like to think that our acts, our decisions, are guided by sound rational thinking but we tends to forget that we are also part guided by our pathos. There are times when we suddenly aren't thinking straight and just immediately act based upon the animal instincts in all of us. We can see this in history repeated over and over again.
 The "rational" Jacobin revolutionaries whom proclaimed that they value human life, only to guillotined so many heads in the French Revolution. Or in 1914 when everyone thought the assassination in the Balkan was just a little thing that won't erupt into a major war, only to find that small event snowballing into major event because every states start mobilizing because of their fear of each others.Â
Politics has always been guided by human emotions. As students of politics, it is our job to acknowledge this inherent human nature. Many of Clausewitz readers tends to read his book solely for its military strategy value but personally I think his book, On Waris more than just that. I think if I have to rank it, I valued Clausewitz's On War more than Sun Tzu's book because Clausewitz dive deeper into the human mind. To finish this argument, I'd like to add my own thinking into the whole argument: War is an expression of the will of the people.
