Unarmed protest is always an option. It’s a harder option, but it is an option.
Hamas could keep their weapons, and target actual military targets in Gaza.
Israel already withdrew from Gaza in '06, but Hamas is happy to launch rockets at civilian targets in Israel.
Hamas could launch rockets at civilian targets in Israel from non-civilian locations in Gaza, instead of using schools and hospitals.
Hamas has consistently picked the most hostile options because Hamas doesn’t just want a free Palestine, Hamas wants the destruction of Israel and rejects any territory existing as an Israeli state. Gaza isn’t even fully isolated by Israel, but Egypt wants nothing to do with Hamas either.
I’m not even saying armed resistance is wrong, but what Hamas does is. And yes, Israel’s government is also just as wrong, if not more so.
