You must’ve heard that completely out of context. The following are some excerpts of what Rav Avigdor Miller wrote in his Seforim:
From: SING, YOU RIGHTEOUS
46. Question: Does not Zionism, or the State of Israel, present ideology which could preserve the Jewish identity?
Answer: Even if it did, this would be a purely artificial ideology and could not appeal to a rational and truth-seeking mind. What right do atheists (i.e. Zionists) have to claim a land, unless by force of arms? It is not an ideology but an organization, and it cannot logically demand allegiance. There is no reason, according to such an artificial ideology why Jews should not lose themselves among the gentiles by assimilation and that’s why a number of Zionist leaders took gentile wives. It is logical result of this lack of rational foundation that so many of the Israeli-born youth leave the country and are lost among the nations. The State of Israel presents the greatest peril to Jewish existence in history.
47. Question: How is that possible?
Answer: Never before were Jews under the influence of such a powerful group of Jewish atheists. The Yevesekzia (Jewish communists) in Russia combated Judaism and urged assimilation, and they ruined millions of souls. But the leaders of the State of Israel speak Hebrew and proclaim themselves the true Jews, and they declare that no belief in G-d and in a Torah is necessary to be a genuine Jew.
From: AWAKE MY GLORY (CHAPTER: THE LEADERS OF ISRAEL)
In July 1938 President Roosevelt convened the Evian Conference to consider the problem of Jewish refugees. At that time a German offer was made to release Jews at $250 per person. The Jewish Agency, headed by Golda Meir, decided to ignore the offer.
At this conference, the delegation from the Jewish Agency made no effort to influence the United States or any of the 32 other participating nations to open their gates to admit German Jews.
769. It was because European Jews put their trust in atheistic Zionist leaders that these leaders everywhere became the lackeys of the Nazis in all the Ghettos. They were the machinery, which served efficiently in the task of keeping the Jews docile and of persuading and coercing them to be sent off to their deaths.
