The simple reason is that he is tired of kicking the can down the road. Decades of being attacked, retaliating but only inflicting enough damage to buy a couple of years and then another attack. Oct 7 and the savagery changed all that. He / Israel has had enough and the policy was to wipe out hamas. You can disagree with that as many have after the emotional shock of Oct 7 wore off and the unusual high death toll of palestinians started to mount. But most people didn't know that hamas was hiding under hospitals, religious houses, schools, etc. where they couldn't be attacked without causing people like you and many others on this board to scream stop because of the palestinian deaths that was inevitable. Nothing wrong with that and it is certainly a logical pov. However, Israel was faced with two options if they were to achieve the goal of wiping out hamas. Root then out door to door and suffer high casualties or bomb them and suffer fewer israeli deaths. Not unlike the decision Truman faced but on a much smaller scale. Palestine, in its depressed state sold its political soul to hamas because it thought hamas was going to offer the best option of an improved economic way of life and that hamas was dedicated to achieving a palestinian state. The PA in the WB offered zero options and was feckless in influencing hamas. The miscalculation and tragedy is that hamas didn't give a damn about the palestinian people except in how they could be used and exploited in their goal to attack israel. That has become easy to see now.
Oct 7 will turn out to be a terrible military decision for Iran. They failed to understand how far they could push before israel before it was to far. You characterize it as genocide and from a palestinian pov I can understand that. You also have to understand israel's view that it is existential to them and they will no longer live beside someone who would commit another Oct 7. You don't have to like it or agree with it but to act as if that isn't a rational thought then you are being intentionally obtuse. Is israel justified in killing 100 palestinians in its effort to kill 10 hamas fighters hiding under a hospital? To you obviously no. But to israel it feels its existence depends on it. You acting as if hamas and iran didn't bring this on the palestinians is just wrong. Before Oct 7, israel wasn't bombing schools and hospitals for the hell of it. You acting as if the palestinians don't share in some of their fate is also wrong. The PA didn't have a charter of the elimination of the israeli state. Hamas did and you can't align yourself with that knowing you are caught in the middle. You continually act as if all of the suffering is at the hands of israel when it just isn't.
