There's been a lot of revisionist history with the World War 2 and the Cold War that really understates the USSR's instrumental role in defeating Germany.
Fascism was popular in the US. Henry Ford shared his thoughts by publishing The International Jew [1]. Hitler was a fan. Ford was mentioned by name in Mein Kampf. We had the Business Plot [2] in 1933. There was a Nazi rally at Madison Square Garden in 1939. The German American Bund was present until 1941.
On the other side of the Atlantic, Stalin had initially sought an anti-German alliance with Britain and France but was rebuffed, leading to the deal with Hitler.
The US had ~400,000 casulaties in the European campaign and none really until D-Day in 1944. The USSR lost somewhere between 26 and 30 million people in WW2, something only really revealed by a 1959 census. Had Germany defeated the USSR and taken MOscow in 1941-1942, we would live in a very different world.
The result of World War 2 was that Hitler lost but the fascists won. Under the guise of fighting Communism (eg the Truamn Doctrine, leading to the Korean and Vietnam wars). NATO was an imperial project. Charles De Gaulle (in the 1960s) went so far as to say Western Europe was in danger of becoming a US protectorate.
We all know about Operation Paper Clip (I hope) but less known is how Nazis found their way into NATO. Adolf Heusinger went from Hitler's Chief of the German High Command to Chairman of the NATO Military Committee. And he wasn't the only one [3].
So when that commenter called the Cold War "retarded", I suspect they're referring to how the US took up Nazi Germany's fight against Communism.
The whole Red Scare was terrible for average American citizens. It was used to dismantle the labor movement and unions and ultimately led to Nixon, Reagan and Clinton and the destruction of real wages and living conditions.
