Who Creates Jihadis?

For all the talk among the Left about how our liberation of Iraq mobilized jihadis around the world to fight us there, the body counts of the jihadi fights against America or Syrias dictator Assad is illuminating.

Perhaps 27,000 insurgents died in Iraq during Iraq War 1.0. This includes Iraqi insurgents, so the foreign total is far less than this.

In Syria, 52,000 foreigners fighting to overthrow Assad have died so far.

So who really inspires jihadi hatred and recruitment?
