How exactly do you propose solving this problem of religion?
Forced conversion at rifle point?
How exactly did humanity solve the problem of Nazi? A hateful ideology that involves belief in the supernatural is not that different from a hateful ideology that involves bullshit belief in a superior race. Note that Nazi ideology wasn't wiped out
completely. It is impossible.
Also note that there is Islam, the cultural skeleton of Palestinians and various hateful subvariants of Islam that are not a cultural skeleton but a parasite on that skeleton.
I'm Irish, I know perfectly well how the British attempts to forcefully convert the Irish to be Protestant went. It backfired horribly. The more they tried and the harshier measures they enforced the more fanatical the Irish Catholics became.
This is why we need to talk about deradicalization and secularisation not criminal forced conversion to Judaism or Atheism. I don't believe in any long-term peaceful solution in Palestine that doesn't involve moderate Islam
The issue here is the Muslim fanatics, and fanaticism is not something you can ever fix with soldiers. You can only intensify it. They fixed it in Germany and Japan not with soldiers but with endless convoys full of food, medicine, and fuel.
Note that the Soviet-occupied part of Germany were't that lucky, they were not treated with respect to their sovereignty, but Nazism still went away. Also, soldiers and tribunals were the first steps of fixing it. Without soldiers sending convoys would do nothing.
But I reject the notion that being kind to defeated enemies guarantees that they will stop being your enemies. Germans and Japanese could still choose the way of armed resistance. They didn't.
The Palastinians have to try and reconcile the image that Hamas preaches of 'Evil Jews out wipe us out and they can only be safe when all the evil Jews are gone' with the constant blockade, poor access to water frequent seemingly random bombing into one of the densest urban environments on earth with no thought for collateral damage and now full on ethnic cleansing.
There was no full blockade, many Gazans worked in Israel and had numerous chances to see who Jews really are. Also, Gazans are not small children, they should understand that when some of you cheer and scream "Allahu Akbar" when rockets are flying to Israel, there will be "seemingly random" retaliation. Also, there is no full-on ethnic cleansing in Gaza yet, only mixed signals suggesting some "soft" forms of it possible after the war. No, wartime relocations are not ethnic cleansing. They become such if they are maintained after the war.
I have said quite a few times what I believe needs to be done in Gaza after the war: Benelovent occupation involving moderate Arab countries (or at least heavy involvement of Israeli Arabs), rebuilding of Gaza for Israeli and international money (not through the government of corrupt Palestinian Authority), educational reform with no UNRWA\PA involved. Support for new political movements which are not Hamas or Fatah. Propaganda of moderate (aka real) Islam by foreign or existing moderate Palestinian Imams. Do I believe that it is what Israel will do? I am veeeeery skeptical of that. Some of their words indicate that it is roughly the plan and then they go spew "brilliant" ideas of resettling Gazans to Kongo. In any case, it is hard to predict what will Israel look like politically after the war. Like someone who monitors the Israeli segment of social networks, I'll be shocked if Bibi will stay in power so his personal plans are largely irrelevant.
How about we try it first?
It is like trying peace talks with Hitler in 1943. It is impossible before the Gaza war is over and Hamas will be stripped of political control over it.
