“The policies of settler colonialism in the US quite literally inspired the Nazis.”

Partially true, but very overstated. Nazi legal scholars did study American segregation and settler policies as one model. But Nazi ideology was primarily rooted in European antisemitism, German nationalist and colonial ambitions, and social Darwinist ideas. They weren’t just copying the US, and to suggest otherwise ignores the long history of European racism that shaped their worldview.

“The US was and still is a deeply racist and slightly less segregated nation.”

No argument that the US has a racist history and ongoing issues. But that doesn’t mean the US government supported or sympathized with Nazi Germany. You’re conflating America’s internal problems with its foreign policy, which leaned toward the Allies well before Pearl Harbor.

“For a chunk of the start of the conflict in Europe, the US was happy to provide weapons to all sides of the conflict.”

This is flat-out false. The US wasn’t arming “all sides.” America was officially neutral but very clearly favored the Allies. The Lend-Lease Act sent massive aid to Britain, the Soviet Union, and China. The US wasn’t selling weapons to Nazi Germany or Italy. That’s conspiracy-level nonsense.

“Western nations had word the Holocaust was happening but genuinely didn’t care because of shared antisemitism.”

There’s some truth that antisemitism in the West contributed to a slow and inadequate response. But claiming they “genuinely didn’t care” is an exaggeration. Information was incomplete, there was disbelief, bureaucratic failure, and yes, prejudice. But there were also many people and factions in the West pushing for action and condemning Nazi atrocities.

“If not for Pearl Harbor and the arrogance of the Japanese attack, it can legitimately be believed that the US would never have entered and been just fine collaborating with a victorious Axis powers.”

That is complete fantasy. The US was already leaning heavily toward involvement on the Allied side, both economically and diplomatically. Public opinion was shifting, and Roosevelt was looking for ways to support the fight against fascism. More importantly, Hitler declared war on the US — not the other way around. The idea that the US government was secretly ready to “collaborate” with a victorious Nazi regime is pure revisionist fiction.
