No, you are putting words in my mouth and being very reductive. Majority of powerful people is not jewish nor zionist, but there is probably a lot of zionists amongst them. And no, not all jews are zionists, nor all jews are in powerful positions.
From https://en.wikipedia.org/wiki/Christian_Zionism
> Christian Zionism is a political and religious ideology that, in a Christian context, espouses the return of the Jewish people to the Holy Land.[1] Likewise, it holds that the founding of the State of Israel in 1948 was in accordance with biblical prophecies transmitted through the Old Testament: that the re-establishment of Jewish sovereignty in the Levant—the eschatological "Gathering of Israel"—is a prerequisite for the Second Coming of Jesus Christ.[1][2][3] The term began to be used in the mid-20th century, in place of Christian restorationism, as proponents of the ideology rallied behind Zionists in support of a Jewish national homeland.[1][4][5]
