What disengagement? Israel controlled their borders, ports and airport, was able to control water, food, energy and aid going in. If that's a disengagement, then yeah, don't be trying that elsewhere, I wouldn't suspect it would work well.
Sure mate, sure.
They did not have a free border with Egypt, their Muslim brothers, not at all.
If you want the long answer, this is a prime example of the looney tunes logic Western people decided to adopt.
The logic that shapes simple facts and reality, clear as fucking daylight, upside down on it's head.
Gazans could have built Gaza from 2006 to be a thriving riviera, nothing was closed, Israel closed what it could only after Hamas won elections, shot rockets and vowed to destroy Israel and kill every Jew on earth.
Israel never controlled the huge border with Egypt, the Egyptions were the ones who closed it because even they understand what you looney tunes over here don't, that the Jihadistic Muslim Brotherhood ideology was and is the overwhelmingly popular ideology in Gaza, and Egypt did what it could to limit their power in the hopes that the people would stop volunteering and supporting Hamas.
This is clear, just like it's clear that in every poll prior to October 7th, Israeli citizens supporting peace and 2 states (not that I support it) were the majority always, while Arab pools showed the other way around.
Just like how Israel accepted every partition plan and Arabs rejected.
Just like how it's a-priori clear that the democratic state is the one that will always strive by definition to avoid war and the other population with the shit culture that allows terrorism to rule through zero accountability will always harm any chance for normalization.
Just like how Israel tried in Oslo, and then again and again for centuries to make peace.
Just like how Israel can take every Arab tomorrow and put them in Jordan (the original Palestinian state) but doesn't, whilst Arabs would allow Hamas to take every Jew and throw them to the sea tomorrow if they could.
The blame is clear, justice and what's right and wrong is clear.
Only thing that is left is blinding hate for just how successful the Jews are.
