Do you know about Palestine? It's a nation where Arab peoples have lived for centuries. Israel conquered it in 1967

Some corrections of factual errors:

By Palestine I presume you are referring to the area which historically has been known as Judea and Samaria where Jews have also lived for millenia, as a matter of fact Judea, previously the kingdom of Judah, is the root of the word Judaism.

Judea and Samaria are part of the lands granted to the Jewish people by the League of Nations for their national home in the Treaty of Sevres 1920. In 1948 Israel declared independence and was immediately attacked by six Arab armies one of which was Jordan who illegally occupied Judea and Samaria. The occupation ended after the Six Day War in 1967 and Judea and Samaria were liberated and returned to Israel by formal treaty in which Jordan renounced all claim to the area and acknowledged the west bank of the Jordan river as Israel's western border.

There is no country named Palestine today, hopefully one day there will be and it's people will live and prosper in peace with their neighbours.
