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.
