There is a difference between courage and heroism.
Courage is the determnation to defeat a dangerous enemy. Heroism involves justice. There is nothing just about any part of this war. Nothing Israel has done has been just. Nothing Hamas has done has been just. Ths war is unjust for all concerned.
The world is against this war. Hamas took over because the people of Gaza were tied of being incarcerated in Gaza. Like Trumplings, they wanted STRONG LEADERS and Hamas was at least punishing the Israelis with their rockets. Netanyahu was also elected because some gullible Israelis also wanted a STRONG LEADER, so Netanyahu did all he could to make himself stronger, by subjugating the Supreme Court. But he was careless and not strong, because he failed to protect the borders, and Hamas attacked.
Israel will have to create a system of government that Gazans will accept and Israel can tolerate. Every building the Israelis destroy, every Palestinian woman or child or noncombatant that Israel kills makes a stronger enemy of the Palestinians it affects.
Israel cannot win this. Hamas cannot win, either.
The only viable fair solution is a two country solution, but the violence has prevented that. Will the fighting continue until all the violent people on both sides are dead? I do not think that has eve happened.
