But it strikes me as odd that Nazi propaganda, even this early in the war, already claims America intends to enter it on the side of the allies.

Hitler wrote a second book after Mein Kampf, which was never published, and was discovered after the war during the Allied occupation of Germany. My understanding is that Hitler believed that the “final struggle” of the war would be between the Third Reich and the United States of America, “a mongrel nation”. Not having actually read the book I cannot personally vouch for the accuracy of that information. But is is possible that Hitler was expecting a confrontation with the U.S., and that is why he so lightly declared war on the U.S. on December 11, 1941, days after Japan had attacked Pearl Harbor. His alliance with Japan was defensive only, and did not require him to join Japan's offensive war.

"My understanding is that Hitler believed that the “final struggle” of the war would be between the Third Reich and the United States of America, “a mongrel nation”. "

Yes, I think you have the right answer.

Like you, for many years I've read about Hitler's two books, but never actually read either one. My understanding is they are rambling and difficult to follow, not to mention thoroughly repulsive. So I've been satisfied to read extensive excerpts.

But the key point is that war with America was part of Hitler's plan from the beginning.

Among the pieces of evidence for this were the Amerika Bomber projects:

"Possibly the first public reference to the Amerika Bomber was on July 8, 1938 in a speech by Hermann Göring saying,

"I completely lack the bombers capable of round-trip flights to New York with a 4.5-tonne bomb load. I would be extremely happy to possess such a bomber which would at last stuff the mouth of arrogance across the sea."[1]

"Canadian historian Holger H. Herwig[2] claims the plan started as a result of discussions by Hitler in November of 1940 and May of 1941 when he stated his need to “deploy long-range bombers against American cities from the Azores.”"

Finally, we should note, the idea of invading the US was part of German General Staff war planning since around 1900.
So Hitler was not an original thinker on this matter (or any other matter I can think of).
