Since you're being extremely condescending, I'm going to point out that this does not mean what you think it means:

> a Jewish homeland in Palestine

This does not mean a Jewish state, as anyone who has read even a little bit about the history of Zionism knows. The term "Jewish homeland in Palestine" comes from the Balfour Declaration, and the point of inventing this term was that it implies some sort of Jewish community in Palestine, but doesn't specify that that community will have a state. It doesn't even state where in Palestine that homeland will be. Part of Palestine? All of it? It's unclear, and intentionally so.

So when you bring up Einstein supporting a "Jewish homeland in Palestine" as proof that Einstein supported a Jewish state, you're just revealing that you don't even know the basics of the history you're trying to discuss.

> The Jews, acting like responsible adults, prepared for the worst-case scenario and, rightly so, prepared an army.

Okay, so the condescending tone continues. Another way of putting this is that the Zionist movement was aware that what they were doing - attempting to establish a state on someone else's land - was so unacceptable to the local population that it would inevitably mean war. Yet they persisted in this policy anyways. By the way, this is one of the central reasons Einstein gave for rejecting a Jewish state. He said that the establishment of a Jewish state in a land that was majority non-Jewish was unjust and would lead to violence. He was correct on both counts.

> At the end of the war roughly 20% of Israel population were Arabs, so obviously you are lying when you say that they went “town by town”. Why are you lying?

The fact that Israeli forces went town by town expelling the Arab population is very well established. There are records of how this happened in countless villages all over Palestine.

Without the expulsion, a vast majority of the population of the territory that became Israel - far more than 50% - would have been Arab. The 20% of the population that was Arab after the war was a small fraction of the original Arab population. In fact, about 80% of the Arab population was expelled.

> and you ignored, all the land that was captured from Israel was ethnically cleansed from Jews.

No land was "captured from Israel." There was no Israel before the war. It was the Zionist forces that were seeking to capture territory to establish a state, against the will of the overwhelming majority of the native population of Palestine. There were small numbers of Jewish people who were expelled from the parts of Palestine that ended up under Arab control, but that was practically nothing compared to the number of Arabs who were expelled.

> And there was a mass explusion of 900,000 Jews from Arab counties.

That happened over the following decades, and it was caused pretty directly by the establishment of Israel. The expulsion of the Palestinians by Israel caused a wave of antisemitism across the Middle East, which led Arab governments to start taking their own oppressive measures against their Jewish populations. One of the tragedies of Zionism is that it undermined the status of Jews in the Muslim world.

> What I really find it puzzling that you might have some good arguments to the peaceful nature of the Arabs, that they were all loving and caring.

Where did I ever say they were all "peaceful" and "loving and caring"? They were normal people. They would fight under some circumstances. One circumstance under which almost any group of people anywhere would fight is when another group of people comes in and tries to conquer their territory.
