“very poor and corrupt Palestinian leadership” – yes. It’s often said that power corrupts. So, I think, does powerlessness. You may have noticed that in organizations with very little power in the wider world, the leaders, and would-be leaders, fight hard for what power there is.
As for Elizabeth Warren, I would ask her the question I’ve asked Canadian political leaders: What’s your Plan B? When you can no longer pretend to think there’s ever going to be a Palestinian state, what then?
People who support, or say they support, two states actually support the status quo, i.e. Israel’s continuing theft of land, water, livelihoods, and lives.
