And indeed, most "nations" have their own homeland. That's exactly what happened in the 19th and 20th century - a new nationalism was taking hold in the world, and many nations created a national homeland - hence the creation of so many countries in the 20th century.

The Zionist movement started because early Jewish leaders saw this phenomenon gaining traction, and understood that as these national identities were created and states started being created for them, many wouldn't consider Jews part of their "nationality", therefore Jews also needed a national homeland. This was, in retrospect, the exactly correct analysis, given the pogroms that happened in the 19th century and given the Holocaust.

Despite so many people claiming otherwise, there's not much different about Israel than many other European nations.
