There are plenty of companies with R&D centers in Israel. Including Chinese companies like Xiaomi.
Haven’t heard of anyone closing up shop.

That’s crazy because I’ve heard Israelis assert the exact opposite.

Yes, religious extremists exist also in Israel.

There’s a certain dramatic irony in funding UNRWA, paying Israel to bomb UNRWA, and then claiming you’re the only folks providing aid to Palestinians.

I’m not the one who wrote USA is the only one providing aid.
What you quoted is the reality. The bulk of the funding over the years has been from the USA and the EU.

So Palestinians are Hamas?
Why is Iran not helping Fatah?
Their support of Hamas is on ideological grounds. Israel is holy waqf land that belongs to Muslims and should be cleansed from Jews.

Even when Egypt had sovereignty over Gaza they made sure to prevent Palestinians from going to Egypt.

Tunnels from Lebanon… to Gaza…? Where’d you read that?
Hezbollah begun bombing Israel in support of Hamas. They’re also funded by Iran (much more than Hamas though).
Meanwhile Palestinians live in camps in Lebanon. Some of those walled and surrounded by watchtowers.
They have less rights there than anyone else (including refugees and migrant workers), despite living there for 3 generations at this point.

Turkey under Erdogan has been mostly hosting Hamas leaders while bombing Kurds in Syria.

I don’t think much needs to be said about Assad.

The only country in the area which actually helped Palestinians was Jordan. Although that also changed for a while after Black September.

Most of UNRWA’s funding over the years has come from the EU and USA.

Hamas is a branch of the Muslim Brotherhood. It wasn’t “invented” by Israel. And Israel didn’t fund them, but it’s true that Bibi let Qatar money reach Hamas when he could’ve blocked it.
The belief among some of the ones who supported that, was that better conditions of life in Gaza would prevent them from going to another war - An article about it from 2015

which happened once by likud activists.
and yet more arab israelis voted than ever before in the election after that.

missed out an important part:

…the overall vote in many of these cities was not for right-wing parties – it was simply split between multiple candidates on the Center or Left.

not quite.
last elections 70% of eligible voters voted.
likud has gotten around 24% of their votes.
this was about the same even in the election before that.
