This was the Palestinian leadership in action. So much history continually untold (and current stuff ignored, such as the "death to Israel, Israel doesn't exist, Jews drink the blood of Palestinian children during Passover" curriculum practically from the cradle) because it doesn't fit the poor refugee narrative.
The media will always make this a ‘sides’ issue rather than the fact the Palestinians are and always have been a community of terrorists that Groups like Hamas and Al-queda can call up any time they want a conflict started.
