How do folks feel about the way that Israel has handled the Palestinians more generally for the last few decades? There's no excuse for Hamas' actions (and their beliefs regarding genocide against Jews generally), but if we are going to support Israel with more than just words, as we obviously are currently and have since their founding, should we not put strings on that aid, such as a requirement to end the current regime of apartheid? There are no good solutions to this problem, but it seems the recently attempted ones aren't working, and I'm doubtful a heavier boot will fix things. But I'm no expert on these issues.
I'm far from being an expert either, but the biggest mistake I think Israel made was in permitting Hamas to take over Gaza and (porously) walling themselves off from a totalitarian sharia state while creating an intelligence blind spot for themselves. You don't give this enemy time to prepare- they aren't going to back off their genocidal intentions simply because they were "left alone". Israel was warned about this, and for whatever reasons- likely politics- they chose not to heed.
None of that excuses in any way the barbaric acts of Hamas, nor the destabilizing force behind them, Iran. I don't buy the "humanitarian purposes only" line of BS regarding the $6B in unfrozen assets either. If you gave me money to pay the utilities, I'd have more money to spend on guns and ammo. You didn't give me money for gun stuff, but I wound up with more all the same. Iran needs to be sanctioned, frozen, and cut off to stop its bad behavior.
Unfortunately, I see all of this as just another turn of the wheel- Israel will respond righteously, and justifiably so. Until, they go too far in the eyes of the world, and get pressured into coming to the table to discuss options. I'm no fan of genocide, but if we're being intellectually honest, we know Hamas will use that for blackmail, drumming up sympathy with the appeasers, and rebuilding themselves to do this again in the next 10-20 years, with Iran's help.
How do we break that cycle? I have no answer.
