At the end of World War 2 how did nations around the world have Jewish refugees who were left without homes?

At the end of World War II, millions of Jews were left homeless due to the Holocaust, which decimated Jewish communities across Europe. Many survivors found their homes destroyed or occupied, while others faced hostility in their countries of origin. As a result, nations around the world, including the United States and Palestine, began to accept Jewish refugees, leading to significant Immigration efforts aimed at providing them with safety and new beginnings. International organizations, such as the United Nations, also played a role in addressing the humanitarian crisis and facilitating resettlement.
