Just as all US citizens are responsible for ongoing drone strikes etc

It's a bit more complicated than that. Palestine doesn't have a strong democratic tradition to begin with. Additionally, Hamas is only governing Gaza, not the West Banks. Hamas also suppresses secular Freedom organizations. And ~50% of the people in Gaza wouldnt even be able to vote out Hamas since they are under 18. Then we have the case of Hamas indoctrination, which finds fertile soil in the impoverished and destitute Gaza youth.

All of that isn't to say I support Hamas. I am quite vocal in my disdain for them. But Israel plays a significant part in their success. So does Iran. And let's not forget that the religious right has been torpedoing a resolution aswell, not just the Jihadist organization Hamas. Rabin wasn't killed by a palestinian hardliner.

When did the Palestinians vote last? What were the demographics of that vote? Are you completely confident it was a purely democratic vote or was it the kind of democracy Putin got voted by? Perhaps the kind kim was voted in by? Or do you think Palestinians have an electoral college like the US?
