Hamas has barbarically attacked Israel for years. I find it difficult to see how one can argue Israel is morally obligated to show more restraint in response. But the fact is that they do way way way way way way way more restraint than what they are morally obligated to do. They are an extremely tolerant and patient people in the face of absurd and continued provocation.
Hamas is engaging in an assymetric war, by design.
Assymetric implies that the response must be “disporoportionate” because the Israelis don’t have the luxury of being able to conduct cowardly terror attacks and scurrying back into the woodwork like cockroaches.
