You would be correct were the war about retaliation. It is not retaliation. It is a military operation. It is a military operation to remove an implacable enemy who deliberately positions military hardware such as rocket launchers in and around civilians and civilian infrastructure. This is an enemy who would kill more than 30,000 Israeli citizens if it could. Hamas would kill every single Israeli if it acquired the weapons to do so. We know this because they frequently fire rockets at civilian targets. They are doing so even now as you read this. Hamas would kill every single Israeli even if it meant killing thousands of Palestinians. We know this is true because Hamas leadership has been saying this for decades.
Further, when you compare civilian casualties to other wars, even other wars in neighboring countries, the casualty rate is extremely low.
