I've said all along that a person has the right to defend himself and his family. That war is sometimes necessary to stop evildoers. Under the scenario you describe it's clearly an act of war and the troops should be sent in. There are three paths to be chosen from for Israel imo. They can bow to international pressure and say enough pain has been inflicted and withdraw. Or they can continue until they can completely destroy the group responsible for October 7th, Hamas, while trying to minimize civilian casualties. Or they can do what you suggest, go ahead and kill every Palestinian in Gaza. Then do the same in the West Bank. Then do the same to Hezbollah in southern Lebanon. Looks like they took the second option. Why is it that they, the party wronged repeatedly for decades by Hamas, are choosing the second option rather than your alternative? They've got millions of Palestinians in one small area right now. Why not go ahead and kill them all? According to you it's the logical and right response to do so. For the very reason that all nations have a diplomatic corps. We reason with, understand motivations, work toward resolving conflicts. And we keep trying. We don't become savages who live by the kill or be killed law of the jungle. We want our children to grow up in a safe and sane world. Might doesn't always make right. Good men stand up to evil and put their lives on the line to do so. They don't use their power to bully, dominate, and kill anyone who refuses to bend the knee. We stand up to bullies, we don't become the bully.
