The chief rabbi and founder of the Edah HaChareidis, Rabbi Yosef Chaim Sonnenfeld, leader of the Haredi community of Jerusalem, died a few days later, and Dushinsky delivered one of the hespedim (eulogies) at the funeral.

[4] Dushinsky founded a community of Hungarian Jews in Jerusalem, affiliated with the Perushim section of the Edah HaChareidis.

Dushinsky was known for his strong opposition to Zionism, and spoke to the newly formed United Nations against the creation of the State of Israel.

Rabbi Dushinsky died on the eve of Sukkos, 14th of Tishrei 1948, shortly after the founding of the State of Israel.

A student of Yisroel Moshe, Rabbi Avrohom Yitzchok Ulman is one of the members of the Rabbinical Court (Badatz), which leads the Edah HaChareidis.

Regarding Zionism, the book Vayoel Moshe, written by Rabbi Joel Teitelbaum of Satmar, was recommended by both the previous rebbe and Avrohom Yitzchok Ulman when a new edition was printed in 2002.
