The Ratlines are well documented and are neither speculation nor blood libel in reverse.
Secretary of State Giovanni Montini (future Pope Paul VI for the brain dead) was up to the neck in providing safe passage to top Nazis from Rome to South America.
I am not accusing Pius XII for the events and relationship with the Nazis during WWII. Whatever he has dune DURING WWII was of necessity.
However, The Holy See and RC Church support to Nazi war criminals AFTER Hitler's demise and the end of WWII was out of FREE WILL.
That free will is the issue here. As you wrote yourself, Golda Meir praised Pius XII for saving SOME Jews DURING WWII,not for safeguarding Nazi war criminals after the war and sending them out to South America through Vatican operated Ratlines.
As you wrote, U.S. picked technical skilled Nazis who were the foundation of NASA and NSA, as well staffed CIA with Gehlen spy network.
Vatican decided to help Nazi specialists in another field - Nazis skilled in mass murder and extermination of civilians.
The US helped worse mass murderers and exterminators of civilians - the Soviet Union. As Eastern Europeans say, Hitler wasn’t better than Stalin, but Stalin was much worse than Hitler. Americans killed in Korea and Vietnam can thank our ally “Uncle Joe” for those parting gifts.
