In 1949, Norwegian social democratic representations of Zionism and Israel shifted from mere support to idealisation. Despite the existence of an increasingly voluminous literature on the European left and Zionism, idealisation of Israel has never previously been explained as distinct from more general support. Regarding the Norwegian case, this article argues that idealisation differed from mere support in its implicit message about the status of ‘civilisation’. Support for Zionism in 1947–8 had been founded on the notion that Europeans needed to ensure the survival of the Jews in a Jewish state in order for European civilisation itself to survive. The idealisation of Israel that emerged from 1949 implicitly argued that Israel proved the attainability of the civilisational ideal and removed from European shoulders the obligation to ensure civilisation's survival. For the Norwegian labour movement, the 1949 decision to make Norway a founding member of NATO contributed to making idealisation of Israel particularly desirable.
