Here is were you are getting lots of things wrong:
". And if Jews really were "God's chosen people", then apparently God himself couldn't stand against the might of the Roman Empire." God punished the jews, just like in the holocaust, joking about it is still bad, but we did something that God didn't like, and he punished us, but he did promise our land back, and thats what Zionism is fulfilling here. Also, if that was the case, why did God help Israel during the 1948 Arab-Israeli war? Why did God help Israel during the 6 day war? Why did God help Israel during the Yom Kippur war? And why now is God helping Israel against Hamas? You people don't think. If they werent the chosen people, Israel would not have gotten so lucky.
"when you take over a business, you can change the name of it. You don't have to use the same name it was called before, because you're the owner now." To compare businesses to politics and history is like saying comparing a book to a computer, they have some similarities, but the rest is different.
"The current "Israel" isn't actually "Israel" The reason why Zionism chose the name Israel was to honor Israels history in that land, and to honor the prophet David who is nicknamed Israel.
So please, learn some history.
