Why do Jews believe they have a right to Palestine?

Answer 1

It's the historic Jewish homeland.

It's the equivalent of asking why there are Poles in Poland or Greeks in Greece. Additionally, the Jewish State of Israel is there, which incentivizes Jews to return to the territory.

Answer 2

You mean when they pray? Well, not all do because a lot of temples are not built that way. But when they do it is because the Temple of Solomon was there, and it is an acknowledgement that although the physical Temple was destroyed, the Temple Mount remains the spiritual epicenter of the Jewish people.

Answer 3

Nope. Many Jews live in Israel (what used to be called Palestine).
