Isreal-Palestine is more complicated than Ukraine-Russia. Russia invaded Ukraine using bullshit claims like Ukraine is full of Nazis and parts of Ukraine have voluntarily separated from Ukraine and joined Russia.
Both the Isrealies and Palestinians were legally given the territory by the UK who took it over during WWII (because why not?) After discovering its the only place in the middle east with no oil they traded it to two different nations accidentally. Oops! And then they told the newly formed UN to fix it. The UN divided the country up into an impossible to implement puzzle piece arrangement that Isreal quickly ignored.
They then became an ultra rich nation by becoming world leaders in military weapon design and manufacturing. Because they’re so rich and produce something very valuable, they have a lot of nations who are willing to look the other way in the border dispute. However, Palestine has valid claims still and are definitely being mistreated. Unfortunately for them, they don’t have lots of money or advanced weapons.
