We are coming up to the 85th anniversary of the murder of Yaakov Yisroel De Haan, a chareidi activist who tried working out a peaceful resolution with the Arabs to allow the viability of the Old Yishuv without bloodshed.
From Wikipedia:
Nakdimon and Mayzlish were able to trace the assassin, Avraham Tehomi (1903-1990), then a businessman living in Hong Kong. Tehomi was interviewed for Israeli TV by Nakdimon and openly stated: “I have done what the Haganah decided had to be done. And nothing was done without the order of Yitzhak Ben-Zvi (who later became the second president of Israel 1952-1963)… I have no regrets because he (de Haan) wanted to destroy our whole idea of Zionism” (Nakdimon).
