All wars are economic in motive and in deed . War is a power force to survive or thrive economically . Destroy the enemies economy and you win
I have a wacko theory that 911 was the opening shot by mercenaries(islamic radicals) to draw the US into an expensive money draining conflict, financed by the perpetrators (big banking), enter the appeasers (US political system) to the rescue with "stimulus" (enslaving the US taxpayer)
the motive being to gain absolute control of the production and distribution of US wealth and power (the definition of socialism)
That sounds like the back story of most conflicts in recent history: the bankers and the arms merchants make their fortunes off the Four Horsemen of the Apocalypse.
