When Israel was founded, Jews all over the world went back there to establish their country?

A considerable number of Jews returned to Israel, but some ultra-orthodox people thought it was too early to establish a secular (not biblical) country. Many of them didn't go back (some even thought that the Holocaust might be God's punishment for themselves), and even in the early days of Zionism, they actively opposed this plan. For example, in the British Parliament, Jewish members opposed the establishment of Jewish homes in Palestine in the early stage.

However, the vast majority of Jews helped Israel to establish a country in various ways, and many immigrants from Europe or the Middle East also moved into new homes (millions of Russian Jews returned to Palestine after the disintegration of the Soviet Union). Many people went to the United States on the other side of the Atlantic, and they funded Israel through money or lobbying.
