Israel, contrary to generally agreed upon international law, considers East Jerusalem as a part of Israel. The autochtonous Palestinians living there are eligible for Israeli citizenship which would allow them to vote. However only a tiny fraction has gotten Israeli citizenship as that would legitimise the annexation.

This is absolutely true: there are hundreds of thousands of adults who live within Israeli territory under Israeli control, where Israeli law and order is applied, who are not allowed to vote, have no representation at all, and are regularly subject to lethal violence from Israeli citizens.

That’s not a democracy.
