3. Both groups believe they should be afforded the ''right of return''

Explanation:

Both Israel and Palestine believe that they should be afforded the ''right to return''. The Jewish people considered this land as their historic homeland, and that they have forcefully been removed from it in multiple occasions, so they think they have the right to return in it and own it. On the other side, the Palestinians which are Arab people, have moved in this region with the expansion of the Islam, and have been living there for more then 1,000 years, so they think they have the right to kick out the Jewish people and have the land for themselves as they have been living there for quite some time. In practice this leads nowhere, and the tensions between the two sides are constantly present.
