What you are not getting is that McCarthy was privy to the evidence collected by the venona project.....but at that time the venona project was Top Secret because the government did not want the Russians to know what we were doing.
Thus McCarthy's and Hoovers hands were tied as they had the hard evidence of who, what where and when.....yet, they could not reveal their source.
The NSA's top-secret program called Venona which intercepted messages between Moscow and its American agents proves McCarthy and Hoover were correct.
'The recent publication of a batch of Venona transcripts gives evidence that the Roosevelt and Truman administrations were rife with communist spies and political operatives who reported, directly or indirectly, to the Soviet government, much as their anti-communist opponents charged. The Age of McCarthyism, it turns out, was not the simple witch hunt of the innocent by the malevolent as two generations of high school and college students have been taught.
The sum and substance of this growing body of material is that: Ethel and Julius Rosenberg, executed in June 1953 for atomic espionage, were guilty; Alger Hiss, a darling of the establishment was guilty; and that dozens of lesser known persons such as Victor Perlo, Judith Coplon and Harry Gold, whose innocence of the accusations made against them had been a tenet of leftist faith for decades, were traitors or, at the least, the ideological vassals of a foreign power.
Even moderate politicians who insisted upon the fact -- and argued that these people might have influenced U.S. foreign policy -- were scorned. Sen. Robert Taft of Ohio said, "The greatest Kremlin asset in our history has been the pro-communist group in the State Department who surrendered to every demand of Russia at Yalta and Potsdam, and promoted at every opportunity the communist cause in China until today communism threatens to take over all of Asia." Secretary of State Dean Acheson, a pillar of the establishment, concluded that Taft had joined "the primitives."
The part played by Klaus Fuchs, a high-level physicist, who had worked at Los Alamos, has been known for many years, as has the treason of the Rosenbergs. Nevertheless, for as long as the subject was a hotly-disputed controversy, it was the practice in leftist circles to scoff at the rustic notion that the "secret" of the bomb could be stolen at all. Now we know, thanks to the latest Venona transcripts, that a Harvard-trained physicist named Theodore Alvin Hall was passing secrets about the instrument which changed world politics in the last half of the 20th century.
The disaster brought on by the end of the American atomic monopoly was not lost on the more perspicacious thinkers of the time. In 1947 Bertrand Russell, the British scientist, philosopher and pacifist leader, saw the monopoly as the world's only opportunity for preventing the Soviets from working their will on much of the globe. Noting the nature of "Asiatic communism" (which American liberals were often unable to see in its fullest dimensions), he argued for forcing Moscow into a humane capitulation, even if it took a military ultimatum to do it. But, as the right eye of American politics was blind to fascism in the 1930s, the left eye could not comprehend the nature of communism -- then or later.
And where was Harry Truman? His hagiographers today present him as the plucky, courageous, little guy who stood up to world communism and led America into a new age of cosmopolitan internationalism. It is a description that millions of his adult contemporaries would have found unrecognizable. In fact, the public conduct of the Truman administration became the affirmation of people who said Truman was soft on communism. When Winston Churchill delivered his famous "Iron Curtain" speech at Fulton, Mo. in March 1946, Truman immediately disavowed the former British prime minister. Astonishing as it may seem to those who get their history from movies and TV, the American president invited Joseph Stalin to come to Fulton and give a speech presenting his side of the story. Truman actually offered to send the battleship Missouri to fetch the Soviet tyrant.
Truman also called the investigation of Alger Hiss "a red herring," encouraging the suspicion that the government was not really addressing the communist threat.
Millions of Americans of Polish, Hungarian, Estonian, Czech, German, Lithuanian, Latvian and Ukrainian extraction saw nations to which they had the closest emotional ties come under Soviet thrall, sometimes by actual arrangement with the American government or in the face of a murmured pro forma opposition by Washington.
Starting in Wisconsin, whence McCarthy hailed, the political fire storm he ignited burned brightest where these emigre populations were most concentrated. In the eyes of celebrity liberalism, those up in arms about the government's acceptance of communist ambition were the unappetizing people of the dull world of the lower middle class. They were the piano-legged babushkas of American politics, stolid Slavs and such, thick of finger and numb of mind.
In the ongoing kulturkampf dividing the society, the elites of Hollywood, Cambridge and liberal think-tankery had little sympathy for bow-legged men with their American Legion caps and their fat wives, their yapping about Yalta and the Katyn Forest. Catholic and kitsch, looking out of their picture windows at their flocks of pink plastic flamingos, the lower middles and their foreign policy anguish were too infra dig to be taken seriously.
Once a year these people would hold huge Captive Nation Day rallies in cities across the country, which Democratic politicians of taste and sensibility avoided. The only Democrats in evidence at these rallies of unstylish anti-communists were often dismissed by their social superiors as smarmy, corrupt, machine pols. Auschwitz, Treblinka, Belsen, all the Nazi concentration camps were dismantled, but the Gulag grew and left-liberals like California congresswoman Helen Gahagan Douglas and the editors at the New Republic magazine seemed not to care. Working class anti-communist voters did not fail to notice the disdain with which some of the liberal intelligentsia regarded them. The early 1950s, not coincidentally, marked the beginning of the great outmigration of the blue-collar workers from the Democratic Party.
When McCarthy and his congressional allies began to demand testimony from alleged communists about the infiltration that was real but undocumented (the Venona program then being the most sensitive of state secrets), liberals denounced them for "star chamber" tactics''.
