Recently, Nazi archives from Bad Arolson became available. They have shown that Nazis started with arrests of political opponents immediatelly after getting to the power and creating concentration camps much earlier than 1937.
No one in his right mind could even dream that Hitler will attempt to abolish Roman Catholic Church and install pagan cult with a center in Nuremberg as an officila religion of Thousand Year Reich. Yet, he did. We did not know about this until 2006. Political oponents of Nationalsocialists knew that since 1933.
Catolic Party and Von Papen propelled Hitler to power and Hitler made Von Papen a Vice-Chancellor.
On paper, that meant that Roman Catholics are not the enemies of Nationalsocialists, but allies. In reality, Roman Catholics were Hitler's enemies because Hitler wanted to abolish the RC Church. Also, many Roman Catholics could not tolerate Nazi savagery and ended in concentration camps. Von Papen himself fell in grace with Hitler as early as 1934 after his Marburg speech requesting cessation of Nazi savagery on the streets. Papen's associates were killed and sent to concentration camp and he was forced to resign from his post as Vice Chancellor.
The cards were on the table. That is the situation Pius XII had to deal with - to save The RC Church from destruction by Adolph Hitler.
What you lack in credibility, you more than make up in rudeness. You come to smear the Roman Catholic Church and protest that someone is smearing you? LOL
