You are right there are some Islamic extremists in Indonesia too but If Israel tries to go against the world if won’t help its cause as billions of people will ignore the Israeli state narrative. The US is in your corner at the moment but as global pressure mounts on them too they will start to apply pressure on Israel to agree to ceasefire. The US is the strongest nation on earth but they are not invulnerable and have several enemies that have enough nuclear weapons to turn them into ash too.
Hamas are banking on getting support from Israel continuing to bomb Gaza. They are hoping you keep doing it without giving innocents an out so they can gain the worlds support. That’s why I suggest a safe zone for moderates. That gives Israel an out for protecting innocents while at the same time they can keep hammering hamas.
