Kicking-out-the-Jews-by-Arab-leaders started as soon as the Ottomans left, long before 1948. And what you are attempting to justify is the robbery and expulsion of people innocent of any crime, solely on the basis of being Jews, not on their actions - very different from the situation of the Arabs in Palestine.
A great deal of it was involuntary: Jews robbed of property and savings in Iraq, forced to "voluntarily" give up their property in Egypt (a trick later employed by the Egyptian military against the Brotherhood), and so on.
Part of the motivation was simple robbery. But the other purpose of kicking 800,000+ Jews into a nation of only 550,000 people in a space of only a few years was to starve the little state to death through poverty and dearth of food. It was a difficult few years for Israel. The Arab trade embargo against Jews was felt sharply and new arrivals were often dumped into the recently-abandoned Arab villages (whose former inhabitants were being fed and housed courtesy of the UNRWA, while the Jews got nothing), given a cow and seed and tools, and other than protection courtesy of the Israeli army given very little else, even if they had been big-time businessmen in their former countries.
My point? You're supporting thieves, robbers, and murderers. For fun. Justice would require that you ally with the Jews of Israel instead.
