The focus on a particular location is a religious one (in the scriptures there was a Jewish homeland before Israel or Egypt, and Israel is singled out because God told them to go), but it's also a selective one that ignores all the times God arranged for Israel not to be there; and crucially does not stop and wait for His opinion about the present. It is the most dangerous kind of religious opinion: one invented by us.
Herzl makes no religious argument, he is fairly close to an atheist. That’s why I mentioned people should read the book or a summary before commenting on the matter.
