A: time exists. As the occupation as become more brutal and unjust, the more a reactionary militant force is going to gain popularity. I fucking hate the cops, but I'm going to call them in extreme distress for example.
B: even if they were unpopular, you have to be a special level of hated before you're expelled and 'civil warred'
Yeah, they're the only militant force with any level of power seen as potential liberators from a violent oppressive force that has only served to fuck them over.
Hamas exists because of Israel and Israel's actions, not because Palestinians are some barbaric angry subhumans. They have never even been that popular.
You mean the people that complain about minor details like, I don't know... ethnic cleansing, genocide, tens of thousands of civilian deaths, settler terrorism, white phosphorus, civilian infrastructure being leveled, journalists murdered.
And don't act like "Lil bean Israel was just minding it's own business when all the savage Arabs attacked and they just had to steal more land". It's ahistorical at best and fucking racist at worst.
I'm not going to get fully bogged down in the semantics, but Israel still basically controls the Egypt border.
The US forced a vote, didn't like the outcome, attempted to coup Hamas, and failed. Also, if Hamas is so bad (which they are in many respects), why does Israel fund them and explicitly has a policy of only interacting with them as being the legitimate government?
Easy, they want an unsympathetic enemy that does not want peace. They want to continue the project of taking the rest of Israel for the ethnostate.
You're also assuming I said they are popular when I'm explaining why they haven't been kicked out
