Yes, it sounds like a great and noble idea (and, of course, in some ways it was, at least in the beginning) until you consider the fact that it's not just their homeland and that the act of creating Israel began with the mass killings and expulsion of people who also consider it their homeland, and certainly had nothing to do with the Holocaust or the pogroms that largely took place in the Western world. These people have never been allowed to return, and those who remain have lived under brutal apartheid ever since.
Today, in reality and in practice, Zionism is nothing more than an ethno-religious supremacist, exterminationist ideology. You don't have to take my word for it, you can find plenty of statements from Israeli leaders that outright confirm this and what they want to do. They have taken a lesson from what the Nazis did to European Jews and are applying it in real time.
