The weekly HaOlam Hazeh was a prominent feature of the 1950s, particularly before the elections. Founded in 1937, HaOlam Hazeh was purchased by Uri Avneri and Shalom Cohen in the early 1950s, after which it became an important force in the country. It declared war on the "establishment", that is, the ruling Mapai party and its leader Ben Gurion.
HaOlam Hazeh advocated feistily and loudly for resolution of the Israeli-Arab conflict. It denounced the Mapai government and spoke out emphatically against the security services, which it felt acted in a manner unworthy of a democratic state. It also decried censorship and the law against slander. HaOlam Hazeh was an extraordinary and significant voice on behalf of freedom of the press in Israel. Its exposes managed to disturb the establishment and it did not hesitate to sidestep censorship and hint at knowledge of the "unfortunate affair".
At the height of the election campaign, in May 1955, a bomb was placed in the Tel Aviv printing house where the weekly was produced. Accusations were leveled at the security services for placing the bomb and others that were placed at meetings of the General Zionists, who had caused a coalition crisis following the Kastner trial.
