I consider the Israeli soldiers who enter Gaza on foot without support or backup from the many tanks already there to be exceptionally brave. Granted they are “protected” by satellite and drone intelligence telling them when someone is lurking around the corner, but it is not perfect and it takes big balls to be there. I did see a video of someone, I assume he was in Hamas, killing 10 Israeli soldiers with a grenade launcher, and felt complete revulsion at what happened. OTOH the bombs that are doing the bulk of the killing for Israel are coming from aircraft high in the sky who operate without any resistance. If you’re looking for a body count I would say that is incredibly effective but not particularly courageous.
It’s such a silly notion to claim it would all come to an end if only Hamas would lay down their arms and surrender so they could be lined up and shot. That holds true if Israel would do the same thing! That is not now and probably never will happen. I assume the Hamas fighters figure if they’re going to die, which they ultimately will, they might as well try to take out as many Israeli’s as they can. It is in their charter after all. That’s Hamas’ choice, but not the choice of the rest of the population, the ones being chopped into pieces while the Israelis cry that they’re the only victims, the real victims.
