Quite a lot in the latter, the Palestinian-administeted part which of which, created by the relaxation of direct Israeli occupation of the entire area, is divided into 165 non-contiguous enclaves separated by Israeli-administered security zones and settlements.
If you mean the PA administrred bantustans, well, yeah, Jews, who are universally given the Right of Return by Israel, don't choose to live there. Not really a surprise.
> the only country you complain about
It's the country the topic is about. It's the country that gets the most aid from the US, and that talks about having the most moral army in the world and all that, while arguably being one of the most backwards, still clinging to colonialism [1], carpet bombing a population half of which is kids in one of the most densely populated areas of the world, while some Western obediently censor or derail anything that goes against that utterly infantile and intellectually bankrupt narrative.
> 20% of Israelis are Arab? How many Jews are there in Gaza or the West Bank?
What does that have to do with anything? The standard isn't Gaza, the standard is international law and basic human decency and intellectual integrity, and the responsibility lays where you a.) offer support and b.) where someone claims to have anything in common with you, and where silence would be agreement. So, not Syria, and none of the other nonsense that gets constantly brought up, without fail.
As a US citizen, I fund Israel and I will complain about their actions since they make me culpable in their human rights violations (of which there are many, well documented).
