Historians of the Third Reich have long noted that Nazi Germany's actions on the battlefield and occupation policies were governed both by conventional military and radical ideological considerations. Much attention has been devoted to the problem of separating the two strands analytically, to determining which actions and policies should be labeled as primarily one or the other and which elements within the regime thought and behaved mainly according to conventional versus ideological notions. In recent years it has become common to place German military operations before June 1941 under the “conventional” rubric and to date the “ideological” war from the invasion of the Soviet Union, which began in that month. On the other hand, whereas the German army was once widely thought to have constituted a bastion of conventional thinking even after the ideological war had been launched, scholars have increasingly implicated it in the perpetration of ideologically rooted crimes (particularly the murder of Jews on the eastern front).
