Forgive my ignorance, but what exactly is the Taliban fighting for? Are they mad at Americans because of the American's support of Isreal? On that note, why does the Taliban hate Isreal? Because they are Jews?
They fight for ideology, a hatred for "Western decadence", for passed wrongs they feel were committed against themselves and their families by the West, etc. It's a hate group that is lead by charismatic sociopaths that use propaganda and promises of a greater purpose to recruit lost souls and pervert an otherwise peaceful relgion into a weapon.
At least thats what I thought prior to reading the last few pages, turns out they are just looking for a big bear hug and a couple extra marshmellows for their hot chocolate.
