You would not have seen Americans smoking and joking with Hitler jr and
his gestapo.

You need to go and learn some of your own history:

Americans companies and individuals who lined up to kiss Hitler's butt
included:

IBM
General Motors
Ford
Chrysler
Standard Oil (Exxon)
Du Pont
Union Carbide
Westinghouse
General Electric
Gilette
Goodrich
Singer
Eastman Kodak
Coca-Cola
ITT
Sullivan & Cromwell
J. P. Morgan
Dillon
Read and Company
Union Bank of New York
Prescott Bush, grandfather of George W. Bush

Graeme K. Howard, Vice President of General Motors, published America
and a New World Order, in which he advised that America give full
cooperation to the Nazi regime.

Henry Ford published anti-smeitic books and insisted that America should
support Hitler. Indeed he put his money where his mouth was and many US
troops were sickened to discover in Normandy that the products used to
kill their comrades had been built by Ford.

Henry Ford and Jim Mooney of GM were decorated with the Order of the
German Eagle by Hitler (a great deal of butt kissing involved there).

And then there were Peter Delaney (Waffen SS) and Martin James Monti
(SS), both American citizens and also the American Free Corps, a unit
whose very existence appears to have been suppressed by the USA. Whereas
the British investigated, identified and punished British collaborators.
The US government swept the issue of collaboration under the carpet and
handed out derisory brief sentences to Nazi collaborators.
