is in Deceiving Humanity
With this phrase, there is the common, military interpretation. Military tactics are all, in one way or another, meant to deceive an enemy. Armies would flee, to encourage the others to attack, only to counter-attack with greater force. Land mines are placed on bridges, clear pathways, and whatever might offer rest to enemy soldiers. Camouflage has always been used to give a slight invisibility, ambushes are set up to capture troops accidentally walking, and all types of traps are in use.
Even in sword-fighting, one will find that opponents will fake a lunge, will focus their eye to particular point, to throw off their opponent. Guerrillas build sniper nests carefully into the terrain, while partisans poison wells and raid vulnerable patrols. The military interpretation of Sun Tzu's message has been clear, repeated by drill sergeants, and droned into the students of war academies.
But there is also a moral interpretation one can read from this phrase. All warfare is based on deception. To approach another human being, with the intent to do harm, is itself a deceitful act. There is no honesty in murder, there is honor in pillage, there is no glory or justice in rape and violence. To deceive is to lie, to give the appearance of truth in order make some take from another -- to attempt to inflict suffering upon another at one's personal gain. In committing an act of violence, a person is deceiving.
Where there has been no offense, where there is no justice is taking action, the use of force is also the use of a lie. It exploits the natural atmosphere of harmony, in picking a moment where there is a good chance for a successful war -- it fosters peace, that its future opponent would grow careless and lose their guard.
There had been peace, and none had to consider another as acting violent or possibly becoming violent. And the first to break this order, this peace, is the first to deceive. It is always a deception, as none could prepare for war, unless the song of peace was on their lips -- no one could rely on others, were they to openly state their selfish and violent intentions.
In our modern world, wars can cost millions of lives. The inhumanities of prisoners of war, forced migrations of entire peoples, systems of concentration camps, slavery and genocide -- all of this has produced untold misery and incalculable suffering. States, whether American or European or Asian or African, have been responsible for this unfathomable cruelty.
Governments always advance the interests of the wealthy classes. And in spreading war across the globe, they must be deceitful. They must have the monopoly of the newspapers, the blessings of the church, and the brainwashing of the schools! The means of communication are in the hands of a very few, and this is essential to Capitalism -- a people could not be led to support for such miserable violence, unless they had been disorganized, misled, and deceived.
