“The statesmen will invent cheap lies, putting the blame upon the nation that is attacked, and every man will be glad of those conscience-soothing falsities, and will diligently study them, and refuse to examine any refutations of them; and thus he will by and by convince himself that the war is just, and will thank God for the better sleep he enjoys after this process of grotesque self-deception.”
– Mark Twain
In a place without an overlord, everyone fights, however unfairly, for their share of the pie, since the rules are set and written only by those who get to the top and claim power. History is written by the winners. Justification to annihilate the enemy at all cost is key; this is a winner takes all place.
Such is our world of nations, the perpetual Hobbesian state of pure nature.
