Zionists wish to form Greater Israel also know as the 'Promised Land' comprising all of modern-day Israel, the Palestinian Territories, Lebanon, Syria, Jordan, and Iraq, as well as Kuwait, Saudi Arabia, U.A.E, Oman, Yemen, most of Turkey, and all the land east of the Nile river.
Orthodox, Hassidic and Zionists alike believe that the Jewish Messiah will appear on Greater Israel is formed, and lead the Jews to form a one world government, in Jerusalem.
Some of the requirements for the Messanic age, include, but are not limited to; Every Jew living in Israel, every jew observing shabbat for a whole year.
Contrary to popular belief, Jew's aren't greedy, power seeking parasites just because they like it. There are plenty of Zionists/Orthodox Jews who literally believe if they fulfill their biblical prophecy, they will be rewarded by the Messanic age.
Now, you may ask why Jews have been attempting to undermine Western Society for many years now. The first, is to force Ashkenazi Jews to return to Israel. The first method, was to spread degeneracy among western societies where Ashkenazi Jew's reside, with the thought that either the children of a traditional Jewish family would rebel and subsequently leave the religion, or Jewish families would see this degeneracy, and commit Aliyah(Immigration to Israel) to escape the destruction of the Nuclear family in western countries. Zionists do this by aggressively promoting Israel as a family based, technologically innovative country, free from degeneracy. This is obviously mostly lies(Tel Aviv).
The second, more recent and aggressive method is mass muslim immigration into western countries. Who do Muslims hate more than Christians? Jews. When Jews are being prosecuted by muslims in their European countries, such as the slaughter of Jews in a Jewish grocer near Paris. The Jews, who only want what's best for their family, naturally resort to immigrating to Israel, exactly what the Zionists want.
