I get that, it is just not correct as the Nazi were emulating the US from the start.

Not only did the US provide massive support, it also did a lot of political work. You see before the final solution Hitler just wanted the Jews out.

He sent delegates to talk with other nations about taking them in. When the wealthy Nazi lovers of the US found out about this they assisted in helping revive anti-jewish sentiment around the world. They went around lobbying every nation including the US to not take the Jews in and it worked.

This is what brought about the final solution, but before that the Nazi had a problem with tracking Jews. Que IBM who used their computing power at the time to generate a census system. Those numbers tattooed on Jewish prisoners arms came from IBM.

If that was not enough the Nazi also had a problem with the logistics during the final solution. IBM once again came to the rescue figuring out how many trains of Jews could be executed without backing up their newly designed death camps.

So the US played an intricate role in making the Holocaust feasible. One of the many genocides the US has been a part of.
