Man, please, watch something, anything, outside of your apparently tiny bubble.
Just to get you started, there's the Israeli Defence Minister calling Gazans "human animals" There's pretty much anything Israeli Finance Minister Bezalel Smotrich has said about Palestinians. There's Israel’s president Isaac Herzog claiming there are no innocent civilians in Gaza. There are the influencers and soldiers mocking Palestinians being blown up and dying of thirst. There are the children singing on Israeli TV about annihilating Gaza and how soon there will be no-one there. I could go on and on.
And no, Israel didn't "give back" Gaza. They withdrew, placed it under total blockade by land, air and sea, and made it almost impossible for any real development in the region to take place (obviously no foreign investment is going to take place in a region that is completely cut off from the world and dependent on another nation for water, electricity and goods).
Even those wonderful greenhouses that everybody likes to blather on about, as if all a country needs are greenhouses, are more complex than you've likely been led to believe.
p.s. Turns out I can cross raping innocent women off the list of differences, although admittedly we have to go back to the Nakba.
