The Land of Israel is, as far as I understand it being non-Jewish, a concept going far beyond a name on a map. The Jewish Promised Land is exactly where it is for historical reasons going back thousands of years. The very name "Israel" is biblical, and the connotations for what the idea of the land of Israel means to the Jewish people are similarly historic. If you are talking about a safe zone for European Jews after WWII then that's one thing, but it would only ever be seen as a temporary home with the ultimate aim being to re-establish Israel in the historic land of Israel. If some sort of Jewish state was set up in Madagascar or East Prussia or wherever it still wouldn't be Israel, and the new arrivees would still be saying "next year in Jerusalem", not "let's stay here in Antananarivo".
