If your enemies were powerful rich and happy. How would you defeat them? Might you consider encouraging decadence to weaken your foes? Encourage you boys to diddle other boys rather than raise strong sons? Or perhaps tell women that they can be men rather than home makers raising the next generation of independent capable offspring? What about promoting gluttony? Unhealthy diets. Materialism. Narsacism? Or all of the above in all of the rich powerful nations at all the same time? Thus we observe the actions of those that waged war upon the west and won.
