The US would probably want to keep out of it until the 1996 election is settled at the absolute earliest. The last thing Clinton needs is the republicans gaining anschluss eyes.
Meaning nobody would want to do business with them at all. Europe would resemble a mixture of North Korea in the 1990s and year zero Cambodia. It would be a pariah continent that would take centuries to recover from the Nazis.
No it would be more likely to have Nazi Germany screaming from the rooftops how it is exterminating every single untermenschen and then making all of its European client states comply with threats of something similar happening to them.
That and the Nazis were actually grubbing from the Americans (specifically Robert goddard) than the other way round. Hell if goddard had the resources at the time America would have icbm'd Germany by the 1950s
It would be like year zero era Cambodia trying to compete economically with went Xiaoping era China.
The Nazis would be screaming from the rooftops while they are exterminating every non German in eastern Europe over the course of 20 years and it's client states would he plundering themselves...
To paraphrase a brilliant Warhammer 40K Fanfic, I wonder if this quote would summarise TTL's left reacting to the Soviet Union and Marxist-Leninism.
"No ideology proclaiming equality would demand such horrors be committed in its name"
And Bill Clinton is going to have a massive headache heading into the election. I suspect he's going to implement a "Away for Election - Be Back 15th November!" policy when it comes to the provinces.
As for NAFTA, oh boy...
