That 1000 years of ‘manipulation’ you are talking about is not really ‘manipulations’, those were open/all-out wars. Last few decades we are seeing ‘proxy-wars’, in proxy war there is no clear enemy, no clear battle-ground, its the common public that suffers more than the actual armies. In those wars there was clear out-come after some days/weeks of fighting and country/region would go back to normal life afterwards.
As for spreading terrorism in name of ‘mujahideen’, why don’t you ask Mr Perfect Democracy about the definition?
