It's been 17 years since the last election. Assuming only 18 and up could vote, that means only people current around 34 and up could vote. So the bulk of Palestinians didn't even have a chance to vote in that election. Not to mention that they were given the choice between a corrupt faction (Fatah) and a possible less corrupt faction (Hamas).
I am so afraid this message is getting lost. There has been a deliberate push to paint this latest incident to be the reason that neighborhoods had to be flattened and civilians slaughtered.
