What was the main reason jews migrated to palestine after world war ii?

the formation of Israel has often been a talking point in politics.  After the Second World War, the creation of a Jewish state was decided and mass migration of Jewish people went to live in the newly created state.  However, its formation was quite controversial and a lot of blame was put on the British handling of it, even when the facts are to the contrary.

This influx of people caused problems, namely it forced the nation of Palestine to move and it created conflict with the local Arab population.  The British government supported the idea of a separate nation of Israel, but it stuck to the 1939 White paper polices for political reasons.  Therefore it had to act due to the increasing level of illegal immigration coming from Europe.  Like we see today with the immigration coming from the Middle East into Europe, the people crossing the waters were in ill prepared boats, which often sank, with many loosing their lives.  It was up to the British military, namely Bomber Command to go and save the immigrants, their job was to find them in the waters and then report back their location.  My Grandfather did this job, however, a problem came, with terrorism, due to the British not allowing immigration into the region lawfully (for one it would cause problems with the local inhabitants who lived there for centuries), the British bases came under heavy terrorist attacks, even those who had saved the lives of Jewish immigrants.

Between 1945 and 1948, it is estimated that around 100,000–120,000 Jews left Poland alone. Their immigration was largely organized by those who wanted to see a Jewish state, under the group known as Berihah. They were also responsible for the organized emigration of Jews from other Eastern European countries such as Romania, Hungary, Czechoslovakia and Yugoslavia, many of whom were Holocaust survivors.
