So what?
The Concordat of 1933 was simply an expansion of existing concordats between the Vatican and the German states of Bavaria, Baden, and Prussia. The Vatican had more than a century of concordats behind it at this point (starting with Napoleon in 1814); by the death of Pius XI in 1939 there were 41 separate concordats on the books.
A concordat is nothing more than an attempt to negotiate a legal document to ensure the Church's ability to function lawfully and unmolested with its just liberties intact. Your attempt to portray the 1933 concordat as evidence of sinister Catholic-Nazi complicity is a lie.
The Vatican and OSS were working together to move Nazis from Germany to Italy and thence to South American countries. This has been written about many times in books and news reports. I am surprised anyone could have missed it.
They where in the same bed together while the Jews where being murdered.
from Catholic Encyclopedia
...just as all other laws when properly promulgated bind the people, so concordats, inasmuch as they take on the form of civil laws are binding on the citizens of the country, and particularly the state officials; so much so that any infringement of them is equivalent to a violation of the civil laws.
