There's only 3 problems with this old claim.

1. You have to define 'Israel' quite carefully to make it work. Palestinians in East Jerusalem cannot vote in Israeli elections. Is East Jerusalem part of Israel or not?

2. There are several other democracies in the Middle East, for example Iraq and Lebanon.

3. Some of the countries which aren't democratic, would be democratic, except that representative governments were overthrown by the United States, in part to enforce cooperation with Israel, against the wishes of most of the people in the country. For example, Egypt.

East Jerusalem is ... not a nut anyone here is going to crack.

What do those folks want for themselves? Be part of the Palestinian Authority? (Not the ones I have been doing a remodel with.) Make them part of Jordan?

Jerusalem is disputed territory. That makes it an uncomfortable mess, for more or less everyone.

The region needs more efforts toward peace, and less black and white, good/bad labeling.

East Jerusalemites are in limbo waiting for peace.

It's Jerusalem. It's a strange place.
