If you are upset by my idea that all sides in WWII (and the following Cold War) were socialist, please note that the two major political parties in Germany, after the war, were the Christian Socialists (later CDU and CSU) and the Social Democrats (SPD). Also, the related Christian Socialist Movement is a faction of the UK's Labor Party.

This is less obvious, in the USA, because the parties have the same names they adopted during the Civil War, but their members and voters are also mostly socialists.

Socialism was never renounced, only communism.
