There was never a self-governing country called Palestine. The territory was part of another empire for nearly 2000 years so nothing got "confiscated". Many countries were formed post WW2 that had far less logic than Israel, where a majority ruled and oppressed a minority. Or even, like in Syria with the Alawites, where the minority oppressed the majority. Look at India/Pakistan, where partition saw the displacement of millions.
There was a land called Palestine that had 2 million people living there whose ancestors had done for centuries. Yeah, it was part of the Ottoman Empire and not a self governing state, just like Ireland was part of the British empire and had never been an independent self governing state called Ireland before 1919.
Then we decided to take away 60% of that land and give it to a group of people that had not lived there for 2,000 years.
Again, I ask you to name a single example of something similar that resulted in peace and prosperity?
