> Ultimately Israelis don't have to suffer serious attacks from Hamas. Hamas doesn't have that power, militarily - only gross incompetence from the IDF allows that kind of attack.
While there were gigantic failures that no one denies, possibly to the level of gross incompetence, Israel is also fighting against a real enemy, not some cartoon. Hamas is also smart, is increasingly well-armed, and can wait many years until the next attack. It's not clear that Israel can defend against every conceivable attack that Hamas can mount, and staying completely vigilant all the time is very costly economically, too. (I'll note that Hamas puts a lot of money and labor into these attacks, but they are pretty freely stealing from their people; the Israeli government can't do the same.)
It's true that, on its own, Hamas can't actually conquer Israel. But it can clearly carry out massive attacks that kill thousands and completely upend all life in Israel, and it's possible that they can keep doing this every couple of years.
> So Israel desperately needs to make amends with its Arab neighbors, and it can stop any real attack from Hamas. That makes the situation pretty different and assymetrical.
Actually, Israel is on relatively good terms with all its Arab neighbors (relative to the past), and was on the verge of formalizing those good relations with Saudi Arabia. That's one of the reasons for this Hamas attack - to try and stop the Israeli-Arab peace process, because they feel (very likely correctly) that it leaves the Palestinians in a worse situation.
> It also bears note that, if you judge Gaza as a country, it would not be able to cause any act of agression, as the Israeli blockade alone constitutes an act of war and a casus belli.
Well, they did elect Hamas and fairly quickly start to shoot rockets at Israel. And by that token they are also at war with Egypt.
Gaza isn't a fully independent country, obviously, but it's also not under full military occupation like it was before. People insisting on one or the other usually have a point that it helps them prove, but reality is more complicated.
I do believe that it is directionally true that Gazans could've made far more of their situation once Israel withdrew, and Hamas has basically squandered that opportunity by turning to violence.
