The first civilian president of the CIA, Allen Dulles, was actually a nazi if you did not know.

Here are some fun quotes I found

What he confessed was this. He had not been serving God, after all, when he followed Allen Dulles. He had been on a satanic quest. These were some of James Jesus Angleton’s dying words. He delivered them between fits of calamitous coughing lung-scraping seizures that still failed to break him of his cigarette habit and soothing sips of tea. “Fundamentally, the founding fathers of U.S. intelligence were liars,” Angleton told Trento in an emotionless voice. “The better you lied and the more you betrayed, the more likely you would be promoted. Outside of their duplicity, the only thing they had in common was a desire for absolute power. I did things that, in looking back on my life, I regret. But I was part of it and loved being in it.” He invoked the names of the high eminences who had run the CIA in his day Dulles, Helms, Wisner. These men were “the grand masters,” he said. “If you were in a room with them, you were in a room full of people that you had to believe would deservedly end up in hell.” Angleton took another slow sip from his steaming cup. “I guess I will see them there soon."

Even as the war still raged, in defiance of President Franklin D. Roosevelt’s orders, Dulles took the time for a friendly fireside chat with Wolff in Zurich. Dulles was greatly impressed with Wolff, with whom he struck a secret deal in violation of an agreement among the Allies; Wolff surrendered the German forces in Italy days before the war’s end, enabling American forces to take Trieste. Dulles provided Wolff with U.S. protection, by removing his name from the list of defendants at Nuremberg; thereby saving his life.

Dulles had the highest regard for Germany’s Nazi elite – the Reich’s industrialists, generals, chemists, medical doctors, and engineers – whose research and achievements were mostly in wartime technology, racial hygiene, torture, and genocide. Like the Nazis with whom he had cordial relationships, he had fanatic contempt for Soviet Communism and harbored decidedly anti- Semitic eugenic views. Under the Brothers Dulles’ leadership deadly lawless operations were executed with complete disregard for moral and legal proscriptions, to say nothing about the innocent human casualties that were a consequence of these operations.

However, there was a serpent in this businessmen's Eden, and its name was Adolph Hitler. August Thyssen's son and successor, Fritz Thyssen, was an enthusiastic supporter of Hitler and had been funding the Nazi Party since 1923. Other German industrialists would do the same. It is hard to say to what extent the American investors shared Thyssen's enthusiasm, though it seems likely that most of them were swayed less by ideology than by the prospect that Hitler would be good for business. Either way, the outcome was that many wealthy and powerful Americans wound up supporting a regime that would ultimately become their own nation's enemy, and investing in the very firms that would provide the core of that regime's military machine. Early in 1933, both Dulles brothers attended a meeting in Germany where German industrialists agreed to back Hitler's bid for power in exchange for his pledge to break the German unions. A few months later, John Foster Dulles negotiated a deal with Hitler's economics minister whereby all German trade with the United States would be coordinated through a syndicate headed by Averell Harriman's cousin. With the Nazis enforcing a favorable climate for business, the profits for Thyssen and other companies soared, and the Union Banking Corporation increasingly became a Nazi money-laundering machine. In 1934, George Herbert Walker placed Prescott Bush on Union Bank's board of directors, and Bush and Harriman also began to use the bank as the basis for a complex and deceptive system of holding companies.

The Hamburg-Amerika shipping line, which Harriman and Walker had controlled since 1920, had a particularly high degree of Nazi involvement in its operations. In 1934, a congressional investigation revealed it to have become a front for I.G. Farben's spying, propaganda, and bribery on behalf of the German government. Rather than advising Walker and Harriman to divest themselves of these tainted assets, Prescott Bush hired Allen Dulles to help conceal them. From 1937 on, the Dulles brothers would serve Bush and Harriman in all their covert dealings with Nazi firms. They also performed similar cloaking services for others, like the Rockefellers.

It goes without saying that Harriman, Walker, Bush, and Dulles were morally tainted by their connections with German firms like Thyssen and I.G. Farben, since they both funded and profited from Hitler's crimes against humanity. However, their entire enterprise was corrupt in a more subtle sense as well, in that its very basis was financial fraud on an unprecedented scale. That would have been true even if Hitler had never come to power. The real significance of adding the Nazis to the equation was that it upped the stakes, both increasing the potential rewards for the participants and forcing them into increasingly elaborate deceptions to conceal their frauds.

And this is just the nazi ties, if I got into his guilt elsewhere in the world I'd be here all day

And people absolutely eat it up and will even go out of their way to enforce that narrative online even when they aren’t a paid shill, all while they think they’re fighting the evil Chinese dictatorship.

The sources they referenced were from 1) mainstream Western journalism, 2) original documents from persons/organizations, and 3) declassified government documents; all of which can be independently verified.

People downvoting you for asking if they are a credible source is...weird. Everyone should always be asking themselves if a particular source of information is a credible source.
