Jewish people did not "ethnically cleanse" anyone. Anyone who didn't want to kill them was welcomed to stay as equal citizens in their newly founded state. Israel was not made through terrorism, it was made through diplomacy and fully legal means and within three hours the Pan Arab league declared war and intent to annihilate the new state and kill or expel all it's people. They lost that war. Them's the breaks. "Don't start wars" seems like repetitive advice, but it's good advice. You certainly wouldn't be here crying had they won.
There are historical records on exactly what occurred, and your version is sheer biased codswallop. There was no homes for the hundreds of thousands of Jewish refugees to go. Such homes did not even exist. There was not a million "businesses" for them to take over. This is a cartoon in your head.
Some 700k immigrants came to Israel during the country’s first three and a half years at an average of close to 200k a year after being ethically cleansed from almost every Arab state, which meant in effect a doubling of the Jewish population. 1 in 10 left immediately because things were so awful! They lived in tents and rapidly developed a nation.
And the land was almost entirely not "owned" by those people of which you speak. The majority of it was owned by the state and the majority of the remainder by wealthy foreign landowners from elsewhere in the Arab world. Those people were as exploited as anyone else. They largely did not own homes. They largely owned nothing at all. The majority were recent immigrants themselves. There was virtually no "industry" and certainly no thriving economy.
Your views are a-historical, biased and typical of the "watermelon" brigade who are motivated by their own prejudice rather than either reality or meaningful justice. Sadly this is the attitude that promotes hate, war and intolerance and not peace. In time, your kind will be put back in their box, but enjoy your time in the sunshine. Every new generation of antisemites believes they have nailed it and found the reason hating Jews and treating them differently is justified, and each and every one is wrong.
Israel is an expression of Jewish people's rights to live on the land from which they came. A tiny part of that land actually, which they chose to share with people of other creeds and ethnicities. They have built a thriving and successful state and it's going absolutely nowhere.
Other groups have the same choices and opportunities, should they wish to take them. Should they instead choose to focus their energy on trying to kill or destroy others, then war is the inevitable result. I certainly hope in time they move on from that attitude. I certainly am not in Bagdad trying to suicide anybody to get my Grandfather's shop from 1940 back.
And as a side note if you want people to be polite to you on the internet, don't quote tweet their posts with "I am not reading this". That's aggressive, unpleasant and goady behavior. The victim / perpetrator reversal mechanism is strong in you! And I am impervious to it :)
