How did the Zionist movement gain momentum after world war 2?

After World War II, the Zionist movement gained significant momentum due to several factors, including the Holocaust's devastating impact, which highlighted the urgent need for a Jewish homeland. The international community, particularly through the United Nations, began to support the idea of a Jewish state, leading to the 1947 UN Partition Plan that proposed to divide Palestine into separate Jewish and Arab states. Additionally, increased Jewish Immigration to Palestine and growing support from Western powers further strengthened the movement, culminating in the establishment of Israel in 1948.
