some 150 years ago Jews thought that they are not allowed to make holy land their residents until Messiah appears.
But, later they changed the concept and come up with the belief that they have to prepare ground for emergence of Messiah. There many Jews who reject this belief and still opposes state of Israel.
There are different opinions on the matter. However, even those who say so may be found living in Israel, such as Satmar and Naturei Karta.
The state was founded by a UN resolution in 1948, Israel's subsequent declaration of Independance and their victory over the Arabs in the Arab Israeli War.
Regarding anti-Zionism among Orthodox Jews, 99.9999 percent of Orthodox Jews do not oppose Zionism. It is only the fringe lunatic element called Neturei Karta, with a membership of 20 people, who oppose Zionism.
