Agreed. Even when the forces were more balanced and Hitler had declared war on the USA the German army never stepped foot on the lower 48. the closest they got a few uboats picking off merchant shipping but even that was pushed back after a few months of horrendous American losses.

I'm truly surprised Hitler never tried some sort of guerrilla attack with a small force just to cause chaos and terror in the heartland. it's not like the USA was very well defended at all from any sort of coordinated landing back in the early 40's.

There was a rather incompetent attempt that was quickly rolled up: https://en.wikipedia.org/wiki/Operation_Pastorius

By the point the USA declared war, he had basically just lost the war against the USSR (as it's in those days that his Blitzkrieg definitely ground down, in visual sight of the Kremlin, to add insult to injury). So he just didn't have anything to spare for such an attack.

Hitler made the rather peculiar decision to declare war on the US first, a few days after Pearl Harbor.

Supposedly it was pointed out that their agreement for mutual defense with Japan didn't require them to declare war if Japan was the aggressor. But that was ignored.
