Fanatical Islamist Jihad deprived Arabs of land. They got a surprisingly strong Israel when they tried to destroy it in 1948. It was not Palestinian Arab land. The Turkish Ottoman empire had ruled their for 500 years. Jews and Arabs. Not that much had gone on there until Zionism. The Jews reclaimed neglected malaria infested swamps at the price of many dead. 
The Muslims invaded in the 7th century but did not become a majority in Palestine until a couple of centuries before Columbus. It was disputed land for centuries but the Jewish people are indigenous to the land. It is not be natural law Arabic. 
The Nazi comparisons are absurd.
