Polls show around 40% of American Jews disagree with the ideology of Zionism, which in modern day has basically become the ideology of Israeli nationalistic expansionism.

This is the dirty secret, Zionism was popularized by the Rothschilds in the 1860s in order to acquire the land of Israel from the British Government after the collapse of the Ottoman Empire, the Balfour Declaration is a 1-page historical document that makes this clear. Many Jewish people see this Zionism movement as pushed by the Rothschild et all as functionally hijacking actual Judaism by pretending to spearhead it for power-seeking reasons.
