The Biggest Impediments to an Israeli-Palestinian Peace Accord?

a) A media which is completely controlled by the Palestinian Authority and Hamas and which only allows propaganda and b) an "educational" system in Gaza and the West Bank (also co-opted by the state) which specifies to children as young as five that they have to destroy Israel (and, yes, themselves, too, if necessary) because Allah wants them to.......Yeah, those are my top two.
