For a change of pace from the intense discussion over "is that a real dead baby" and "how many dead babies are acceptable collateral damage before you call it a war crime", lets talk about the cold blooded military reality of the situation.
A lot people have a bad habit of assuming that the interests of Hamas and the Palestinians or the Israeli government and your average Israeli citizen are identical.
If you think of this as "2 million strong ghetto dwellers launch hopeless, insane iron age style raid against vastly superior neighbour" then the only explanation is something to do with sandniggers being suicidal.
But while Hamas may be retarded in many ways, they're clearly following the Bin Laden formula to a tee: drive the people into an irrational rage with terrorism, bait the government into multiple expensive wars to drain its resources and credibility and use the inevitable atrocities to overthrow the secular dictatorships and monarchies across the region. In the short run, Bin Laden looked like a retard hiding in a cave for picking a fight that got his Taliban patrons wiped off the map. But in the long run America wasted trillions of dollars, thousands of soldiers' lives (tens of thousands counting maimings and suicides) and created a chaos vacuum that ultimately empowered Jihadists and the Iranians. After twenty years of American occupation the Taliban ended up with more territory and a stronger grip on power than they started with.
Hamas isn't just sitting in those apartment buildings getting airstruck and going "shit, we didn't consider that the Israelis have superior airpower". Their top leaders are relaxing in Qatar and Iran enjoying the carnage on TV and the top functionaries in Gaza are in the miles of tunnel networks built deep into the bedrock. Their income and power isn't derived from Gaza so they don't give a shit if the IDF flattens every high rise on the strip and they aren't dependent on Gazan tax dollars so they only stand to benefit from civilian casualties which they can use to drive Arabs into a frenzy, or at least prevent any kind of diplomatic rapprochement with Israel. So long as the IDF doesn't literally gas every single Palestinian the survivors will inevitably be highly motivated to join Hamas, so there's another win for them. Some may think that if Israel is just super brutal and doesn't care about civilian casualties that they can therefore take out Hamas with ease but this is wrong.
Case in point, look at 2nd Grozny. The Russians didn't care about civilian casualties and would flatten anything that even looked like a defensive position yet they still suffered thousands of casualties. This is because a flattened building does not magically transform into a flat plain suitable for driving tanks over but thanks to conservation of mass becomes a mountain of debris which can hide guerillas or defensive emplacements. The Russian strategy was to hammer a target with explosives, then send in expendable Chechen loyalist shock troops to see if anyone was still shooting back, return to shelling the area if the cannon fodder get shot, rinse and repeat. Since then the rise of cheap and effective weapons like drones have only increased the cost to take a city. For example in Mariupol the Russians had the city totally surrounded while the defenders had minimal preparation to stockpile supplies and yet they fought for almost 3 months, inflicted serious losses on the attackers and only surrendered when they ran out of water. In the various sieges of urban areas in the Ukraine war it's exactly the same: even with overwhelming superiority in firepower you're basically guaranteed to take serious losses because as that old /pol/ post said, you can't take a city with nothing but drones, airstrikes and artillery, you need infantry to actually secure an area and clear out the enemy.
Historically while the IDF has been exceptional when it comes to air, artillery and even tanks they've had a pretty bad record when it comes to close quarters urban combat and they have a very low tolerance of casualties. The opening of the war in Lebanon back in 2006 looked pretty similar to this: Hezbollah kidnapped an Israeli, then Israel obliterated southern Lebanon with airstrikes and artillery. But when the Israelis tried advancing on the ground they were repeatedly driven back by Hezbollah defenses and by fighters using their tunnel network to pop up behind the IDF and ambush them. After taking a few hundred casualties the IDF gave up and ended up handing over a thousand prisoners in exchange for one low ranking soldier (this is why Hamas went so hard for hostages, by the way). In Gaza 2014 they launched some ground attacks against Hamas, lost a dozen soldiers in one ambush and decided to stick to airstrikes from then on.
To be fair to the IDF, they're an army that can't afford a war of attrition. Israel has a population of just under 10 million but only 7 million of those are Jews and around a fifth (and growing) are ultra-orthodox Jews who don't serve in the IDF and who live off of tax dollars doing nothing but reading the Torah and making babies. They compensate by conscripting a huge portion of the capable population, something that works for a quick conventional war but that means the economy will take a huge hit if they have to maintain a siege or occupation of Gaza for over a month, let alone the costs of any workers in key industries getting killed or maimed. Credit ratings agencies have already threatened to downgrade Israel and if they seriously plan to eliminate Hamas from Gaza then they almost certainly will. In the absolute best case scenario it would take at least a month and thousands of casualties minimum. If Hamas is really prepared or the IDF fucks up then it could take several months, and that's not even taking into account the potential intervention of Hezbollah or Iran.
All this to say that while Israel is definitely capable of eliminating Hamas, the price for doing so will be far higher than most normies expect and it could be higher than the Israelis are willing to pay. It's entirely possible that Israel goes full scorched earth through Gaza and still winds up failing to drive out Hamas.
