The only way they're not accurate is through underestimation. The official figures exclusively count verified recovered bodies. Unidentified bodies, those still under the rubble, and the dead who cannot be processed by the medical system are not counted. That same medical system that was utterly destroyed by Israel. All evidence points to the official figures being a gross underestimation. After taking all precautions and publishing only the most conservative, verifiable numbers with names backing each one, westerners claim based on propaganda alone that the casualty figures are an overestimation.
We don't need to be parroting genocidal apologia from Joe Biden and the imperialist machine.
What you are saying is exactly what was used to justify the Oslo accords. That path has already been tried and the result of it is the traitorous Palestinian authority that you see today. A Palestinian state that's militarily antagonistic to israel will not be allowed to exist while israel has the power to prevent it, and if Israel does not have the power to prevent it, it will not have the power to defend its own existence. There is no need to keep rehashing this same rhetoric.
