A jihad (in relation to how mtw2 uses it ) is not defensive at all in anway its not called to defend a city its called to attack a city and its not always a city that was once muslim at all . The pure mechanics of this game makes a jihad not defensive at all its absurd to even propose its defensive
So to give the good guys would be an altimate lore rape completely this game doesnt follow lore to the dot how can it its a game for goodness sake but why add a feature that is well straight of the bat completely foriegn to the third age . to unify all the good guys under one banner is well just not aplicable at all you could give perhaps jihads to one faction or maybe to the elves so they would work together (thats still not lore correct either but less of a rape.)
I know you have love for this game young master evan but do you ever actually think about what you say or do or does this stuff just pour out with out any though process at all (which is what it seems.)
