The destruction in Gaza is in reaction to the actions of Hamas. Remember, be clear that Hamas have repeatedly stated that Oct 7th was not a one off and would be repeated again and again, and that Hamas and Hezbollah had fired over 30,000 rockets into Israel within one year of the anniversary of october 7th, as well as continuing to send terrorists into Israel to kill civilians.
Hamas deliberately built tunnels entrances in hospitals and schools, and houses and hostages have reported being taken in and out of tunnels through such builidngs. Hezbollah also have a tunnel network in Lebonan
Hamas used the first ceasefire to plant thousands of IEDs in civilian homes and tower blocks. These buildings needed to be destroyed - they would never again be habitable or safe.
Hamas have openly stated how they seek to use civilians as shields and how they need the death of their civilians to fortify their fighters. And we can believe them as they spent many many years and a huge amount of money building a multi layer tunnel network under Gaza of hundreds of miles yet built not bomb shelters for civilians and did not let them in the tunnel network.
Despite Hamas's callous use of the death of its own people for its own ends, Israel, at risk to its own soldiers, has conduced an urban war with the lowest combatant to civilian death ratio of any urban war.
I'm sorry, but the bias against Israel is awful in the way people view this war. People have no interest in exploring any of the context, or why anything is happening, Hamas is completely written out of the narrative of this war, despite the fact that their actions throughout, from start to finish, have dictated how this defensive war was conducted (and of course the fact that it was fought in the first place).
