You should, though, consider the aims and principles held forth by the various governmental statements as early as 1933. The new government did not state as an aim oftheirs that they wanted to kill all Jews and Witnesses and Gypsies and Homosexuals, that they wanted world dominion reached by a World War etc. They wrote about national values, about how church mingling in state affairs had to end, how peace and wealth would be obtained etc. - much as it is done today. Could not each of us subscribe to almost all lofty governmental or presidential inauguration speeches held today? So could the Witnesses of that day too.
In stead of calling it an attempt to support the Nazi state, which is an absurdity, it should be called a failure to see what was behind the lofty speeches, the more or less hidden goals. In the 20s and 30s, in Europe communism was the Great Danger, and for that reason, many were fooled by Nazism as a defence against Stalin. The Watchtower then, as at times now, failed to produce a deep investigation, a thorough research, into Nazism, and held a too shallow view. Some years ago, when the Witnesses were persecuted in benin in Africa, an article in Awake which wrote about this, said that "socialism was declared in Benin on ..." and then gave a specific date. If one is into political science, one would rather easily detect that socialism cannot be declared on a specific date, and then from that date on the country is a socialist one. That is shallow research. That is quoting from a presidential speech where a mumbo-jumbo president says that "today, our country is a socialist one".
The declaration and the surrounding opinions and acts stem not from an attempt of cooperation, but more from the lack of a deeper understanding of Nazism's true nature.
The right-wing parties supported Pinochet's coup d'etat in Chile and his murder of president Allende, as they believed they would have a say from then on. When he began persecuting them as well, they understood their error. In Nazi-Germany, Hitler was supported by the upper class, as they saw him a fitting vehicle in their fight against Communism. Too late they understood their error.
It is so easy to be wise - afterwards.
