Streicher was not a member of the military and did not take part in planning the Holocaust, or the invasion of other nations.

The judgment against him read, in part:

For his 25 years of speaking, writing and preaching hatred of the Jews, Streicher was widely known as 'Jew-Baiter Number One.' In his speeches and articles, week after week, month after month, he infected the German mind with the virus of anti-Semitism, and incited the German people to active persecution. ... Streicher's incitement to murder and extermination at the time when Jews in the East were being killed under the most horrible conditions clearly constitutes persecution on political and racial grounds in connection with war crimes, as defined by the Charter, and constitutes a crime against humanity.[4]
