"Throughout history, war planners have used various forms of deception to trick their enemies. Because public support is so crucial to the process of initiating and waging war, the home population is also subject to deceitful stratagems. The creation of false excuses to justify going to war is a major first step in constructing public support for such deadly ventures.
Perhaps the most common pretext for war is an apparently unprovoked enemy attack. Such attacks, however, are often fabricated, incited or deliberately allowed to occur. They are then exploited to arouse widespread public sympathy for the victims, demonize the attackers and build mass support for military “retaliation.”
Like schoolyard bullies who shout ‘He hit me first!’, war planners know that it is irrelevant whether the opponent really did ‘throw the first punch.’ As long as it can be made to appear that the attack was unprovoked, the bully receives license to ‘respond’ with force. Bullies and war planners are experts at taunting, teasing and threatening their opponents. If the enemy cannot be goaded into ‘firing the first shot,’ it is easy enough to lie about what happened. Sometimes, that is sufficient to rationalize a schoolyard beating or a genocidal war.
Such trickery has probably been employed by every military power throughout history. During the Roman empire, "the cause for war" -- casus belli -- was often invented to conceal the real reasons for war. Over the millennia, although weapons and battle strategies have changed greatly, the deceitful strategem of using pretext incidents to ignite war has remained remarkably consistent.
