Paraphrased: “After decades of colonization, why would Israel publicly state that they were ending all illegal ongoing colonization?”
Because Israel already took most of the land(see picture) and didn’t have to give any back.
Because there was a lot of complaints about them colonizing Palestine, especially as the internet became more popular and people became more aware of the illegal Israeli colonization of Palestinian land.
By publicly stating that Israel would no longer annex Palestinian land, they didn’t have to give up any of the land they already colonized over the past half century, civilians could continue to colonize Palestinian land because it wasn’t official government or military colonization, and people would be mollified.
And it worked.
You apparently aren’t aware that Israelis are still colonizing Palestine because 19 years ago they put out a press release that said “no backsies, but some of us will stop officially colonizing this country after 60 years”.
The civilians are still settling Palestinian land(they never stopped) that has been now evacuated because, you know, they’re killing all the Palestinians.
