The Jews just went back to the home which had been stolen from them and which they have subsequently vastly improved.
The West, certainly in the initial stages, did all it could to stop the Jews from returning to their homeland, from which they had been violently removed by the Roman Empire, from Wikipedia:

"In 66 AD, the First Jewish–Roman War began. The revolt was put down by the future Roman emperors Vespasian and Titus. In the Siege of Jerusalem in 70 AD, the Romans destroyed much of the Temple in Jerusalem and, according to some accounts, plundered artifacts from the Temple, such as the Menorah. Jews continued to live in their land in significant numbers, the Kitos War of 115-117 nothwithstanding, until Julius Severus ravaged Judea while putting down the Bar Kokhba revolt of 132–136. 985 villages were destroyed and most of the Jewish population of central Judaea was essentially wiped out – killed, sold into slavery, or forced to flee.[7] Banished from Jerusalem, which was renamed Aelia Capitolina, the Jewish population now centered on Galilee,[8] initially at Yavneh.
The Jews had very little help from the West, especially the Brits, who in actual fact did all it could to dissuade the Jews from returning and settling in their homeland.
