It’s impossible to say, but it seems likely that the colonial efforts of the Britain, Dutch, Spanish, and Italians would have been directed elsewhere rather than vanishing, resulting in deaths over there instead of over here. I have to think that everything that was first invented/discovered in the Americas would have eventually been invented/discovered elsewhere, but for whatever the delay in time was, people would have suffered/died in some cases. Later, possibly a lot more European Jews in the 40s. It’s an alternative timeline with a corresponding alternative set of deaths.
