I don't think this is a symmetrical situation. Life in Israel is quite comfortable. Young people have hopes and dreams beyond sacrificing themselves in an eternal war. Palestinians in Gaza have an extremely bleak outlook on the future and effectively no hope that anything meaningful will change in their lifetime, and they feel collectively humiliated by decades of occupation. Sacrificing "everything" is a lot easier when everything looks a lot like nothing.
Did you know that Gaza has shopping malls and waterfront resorts? Did you know that Israel had been opening up more and more jobs for Palestinians within Israel? Until they decided to throw all that progress away on October 7th.
Their own state. This is what people keep missing in discussions about this conflict: you don't get your own state by having the world, or Israel, or the US, or Iran "grant" it to you. You get your own state by building it - having functional institutions, developing an economy, reaching out to build peaceful international relations.
Hamas chose to take all that steel and concrete, donated in the billions by the entire world, and build tunnels and rockets instead of universities and civilian infrastructure.

They are 100% dependent on Israel granting them their state. Take electricity for example. Before the current fighting, Gaza was on a rolling blackout schedule where each region only has electricity for a few hours each day. They have one diesel power plant (Israel enforces that all diesel is bought through Israel; it completely controls the supply), and the vast majority of the rest of their electricity needs were met by Israeli power lines (they also bought a little bit from Egypt).
Whatever economic activity they develop that is dependent on electricity (that is, nearly every modern economic activity) must be "granted" to them. Israel can (and has, and currently does) cut off electricity supply to Gaza at will, as a negotiating tactic or as punishment.
Yet, over a million israelis left, and their media complains about it. And yet, we see the pride of the Palestinian people in them facing one of the most brutal regimes in history, they stand tall and strong.
