No, again, that was very much a high cost, low result action.
I was thinking of a reverse
Operations_Grouse_and_Freshman
with the aim of doing something like killing FDR.
I have no illusions that anything other than possibly a high result, low cost raid could possibly work out for the Axis.
The thing is, the US wasn't an occupied country at the time. You don't have the natural vulnerability to recruitment among the populace. Assuming, of course, this is an identical US.
Granted, German-Americans were a large ethnic group, and still are. In the previous world war, there was rampant paranoia that German agents would act against the US government. That alone led to the near complete elimination of German as a first language in the country. Assuming that there is an even
greater German threat, the US would be quite backwards to risk letting an attack come in and demoralize it to such an extent that it would quit.
Just the sheer number of contrivances that would be necessary to facilitate an invasion would be folly. You'd have to have a US that practically deindustrializes before WW1 breaks out, have it completely ignore the plight of Britain and the USSR, refuse to send any form of Lend Lease, never build up its forces in wake of Japanese aggression, much less German aggression, never cut off the flow of Japanese or German funds, never work together with the various governments in exile to defend their colonial possessions (Greenland/Iceland et al).
Then the US would have to (a) ignore Britain as it capitulates and apparently gives the Royal Navy to the Germans (never having worked to ensure that it would go to Canada as they did OTL), (b) never making a move as Germany sets up sizable bases in Former French or British possessions in the New World, (c) allowing the Germans to integrate themselves with the various New World nations and bring them over to their side, (d) never performing any actions of their own to hamper German efforts to integrate their vast empire and keep the various puppet regimes on their feet.
Frankly, it would almost take Draka-levels of obliviousness for the US to never notice or react to everything being drawn against it. Yes, you could create a situation where some group in the US would act against it and start committing terrorist actions against Germany, but the US and the other allies (who do exist. We shouldn't look at the US versus Germany in isolate) would be doing the same thing against the Germans. And the Germans have a lot more people who would want to get their revenge on the (again) occupying forces. Frankly, it would be a covert, Cool War. And, even if the US gets behind on rocket science, they are quite a ways ahead on atomic science.
Everything, basically, would have to go right for the Nazis for
years on end for there to be a chance for an invasion to roll out. And, frankly, even if they do manage to pull a thing off, slip by the various fleets, and land, the US should be able to rive them back. It isn't like their manpower is being split between three fronts, against one implacable foe who keeps sending reinforcements and a mountainous slog on the Italian peninsula and now to the beaches of northern France. And, even if there was a Zimmerman telegraph type of event
again, I'm not sure how much good it would do.
tl;dr, the Germans would have to be so lucky that they make the Japanese in the first few months of the war look like broke suckers.
