An interesting quote:
"Of course common people don`t want war, but after all, it is the leaders of a country who determine what politics will be followed and it is always an easy matter to pull the people. No matter if they have a chance to speak or not, you can always drive the people to do whatever their leaders want. It is easy. All you have to do is tell them that they are being attacked and denounce peace activists for their lack of patriotism and because they are exposing the country to peril"
Hermann Goering, in the Nuremberg trials (1945)
Sounds familiar, uh?
All I mean is, you can`t understand the reason of a war through the excuses that their starters provide. The excuses and the real reasons are totally different things. You can`t start a war "to bring liberty to an opressed people" just like you can`t make a chair with bread: bread is not intended to work as furniture, and wars do not work to bring liberty, peace, safety or any other "clean" thing: they are only a tool to enhance the power of a certain nation.
