Yeah, I agree with this post. It's a really fucked up situation. In addition to what you mentioned, there are the various Arab neighbours of Israel whose policies have mostly made the problem worse. There's Iran funding / supporting Hamas. Syria and Iran funding / supporting Hezbollah. Qatar hosting Hamas leadership. Jordan and Egypt refusing to allow Palestinian refugees into their countries.

The main point I was making was that there's support for Hamas in Gaza because of how badly the Palestinians in Gaza are treated by Israel. The Palestinians in Gaza are treated horribly by Israel, partially to punish them for supporting Hamas, and partially to try to make it harder for Hamas to attack them. A military operation can't defeat Hamas, even if they kill every current Hamas fighter, the collateral damage will just convince more people to join Hamas. The only thing that has any hope of working is to destroy the support for Hamas. But, the Hamas terrorist attack has worked spectacularly. I don't mean how effective they were in killing and capturing Israelis, but in terms of provoking the exact response from Israel they wanted. Israel is playing into the hands of Hamas in exactly the same way that the US played into the hands of Osama bin Laden in its response to the 9/11 attacks.
