Final answer:
The Zionists wanted to establish a new nation due to the pressure of antisemitism faced by the Jewish people around the world. They believed that every religious or ethnic group should have its own country. The establishment of a new nation in Palestine would serve as a safe haven for Jews and allow them to govern themselves.
Step-by-step explanation:
The Zionists wanted to establish a new nation for several reasons, primarily due to the pressure of antisemitism faced by the Jewish people around the world. The movement to establish a Jewish homeland, known as Zionism, began in the late 19th century as a response to the persecution and discrimination faced by Jews in Europe. The Nazi Holocaust further reinforced the need for a safe haven for Jews. Additionally, the Zionists believed in the idea that every religious or ethnic group should have its own country. They saw the establishment of a new nation in Palestine as a way for Jews to govern themselves and live freely as a separate Jewish nationality.
